Install the Native Xen and KVM Drivers

-

Scenarios

When optimizing a Linux private image with Xen virtualization, you need to change the UUID in the fstab and GRUB configuration files, and install native Xen and KVM drivers on the source ECS of the image.

-

This section describes how to install the native Xen and KVM drivers.

-

Xen: If you do not install the Xen driver for the image, the network performance of the ECSs created from this image will be poor, and the security groups and firewall configured for the ECSs will not take effect.

-

KVM: If you do not install the KVM driver for the image, the NICs of the ECSs may not be detected and the ECSs will be unable to communicate with other resources.

-

-

Procedure

Modify the configuration file depending on the OS.
  • CentOS, EulerOS

    Take CentOS 7.0 as an example. Modify the /etc/dracut.conf file. Add the xen-pv and VirtIO drivers to add_drivers. xen-pv drivers include xen-blkfront and xen-netfront. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Save and exit the /etc/dracut.conf file. Run the dracut -f command to regenerate initrd.

    -

    For details, see CentOS and EulerOS.

    -
  • Ubuntu and Debian

    Modify the /etc/initramfs-tools/modules file. Add the xen-pv and VirtIO drivers. xen-pv drivers include xen-blkfront and xen-netfront. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Save and exit the /etc/initramfs-tools/modules file. Run the update-initramfs -u command to regenerate initrd.

    -

    For details, see Ubuntu and Debian.

    -
  • SUSE and openSUSE
    • If the OS version is earlier than SUSE 12 SP1 or openSUSE 13, modify the /etc/sysconfig/kernel file and add xen-pv and VirtIO drivers to INITRD_MODULES="". xen-pv drivers include xen_vnif, xen_vbd, and xen_platform_pci. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Run the mkinitrd command to regenerate initrd.
    • If the OS version is SUSE 12 SP1, modify the /etc/dracut.conf file and add xen-pv and VirtIO drivers to add_drivers. xen-pv drivers include xen_vnif, xen_vbd, and xen_platform_pci. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Run the dracut -f command to regenerate initrd.
    • If the OS version is later than SUSE 12 SP1 or openSUSE 13, modify the /etc/dracut.conf file and add xen-pv and VirtIO drivers to add_drivers. xen-pv drivers include xen-blkfront and xen-netfront. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Save and exit the /etc/dracut.conf file. Run the dracut -f command to regenerate initrd.
    -
    For details, see SUSE and openSUSE.

    For SUSE, run the following command to check whether xen-kmp (driver package for xen-pv) is installed:

    -

    rpm -qa |grep xen-kmp

    -

    If information similar to the following is displayed, xen-kmp is installed in the OS:

    -
    xen-kmp-default-4.2.2_04_3.0.76_0.11-0.7.5
    -

    If xen-kmp is not installed, obtain it from the ISO file and install it.

    -

    If you add built-in drivers to the initrd or initramfs file by mistake, the ECS will not be affected.

CentOS and EulerOS

  1. Run the following command to open the /etc/dracut.conf file:

    vi /etc/dracut.conf

    -
  2. Press i to enter editing mode and add the xen-pv and VirtIO drivers to add_drivers (the format varies depending on the OS).
    [root@CTU10000xxxxx ~]# vi /etc/dracut.conf 
-# additional kernel modules to the default 
-add_drivers+="xen-blkfront xen-netfront virtio_blk virtio_scsi virtio_net virtio_pci virtio_ring virtio" 
-......
    -
  3. Press Esc, enter :wq, and press Enter. The system saves the change and exits the /etc/dracut.conf file.
  4. Run the following command to regenerate initrd:

    dracut -f /boot/initramfs-2.6.32-573.8.1.el6.x86_64.img

    -

    If the virtual file system is not the default initramfs, run the dracut -f Name of the initramfs or initrd file actually used command. The actual initramfs or initrd file name can be obtained from the grub.cfg file, which can be /boot/grub/grub.cfg, /boot/grub2/grub.cfg, or /boot/grub/grub.conf depending on the OS.

    -
  5. If the virtual file system is initramfs, run the following commands to check whether native Xen and KVM drivers have been loaded:

    lsinitrd /boot/initramfs-`uname -r`.img | grep xen

    -

    lsinitrd /boot/initramfs-`uname -r`.img | grep virtio

    -

    If the virtual file system is initrd, run the following commands to check whether native Xen and KVM drivers have been loaded:

    -

    lsinitrd /boot/initrd-`uname -r` | grep xen

    -

    lsinitrd /boot/initrd-`uname -r` | grep virtio

    -

    Assume that the virtual file system is initramfs. The following command output will be displayed:

    If you add built-in drivers to the initrd or initramfs file, the ECS will not be affected. This makes it easy to modify the drivers. However, you cannot check the drivers by running the lsinitrd command. You can run the following commands to check whether built-in drivers are in the kernel:

    -

    cat /boot/config-`uname -r` | grep CONFIG_VIRTIO | grep y

    -

    cat /boot/config-`uname -r` | grep CONFIG_XEN | grep y

SUSE and openSUSE

If the OS version is earlier than SUSE 12 SP1 or openSUSE 13, modify the /etc/sysconfig/kernel file. For details, see scenario 1.

-

If the OS version is SUSE 12 SP1, modify the /etc/dracut.conf file and add xen-pv and VirtIO drivers. For details, see scenario 2.

-
If the OS version is later than SUSE 12 SP1 or openSUSE 13, modify the /etc/dracut.conf file and add xen-pv and VirtIO drivers to add_drivers. For details, see scenario 3.
  • If the OS version is earlier than SUSE 12 SP1 or openSUSE 13, perform the following steps:

    For SUSE, run the following command to check whether xen-kmp (driver package for xen-pv) is installed in the OS:

    -

    rpm -qa |grep xen-kmp

    -

    If information similar to the following is displayed, xen-kmp is installed:

    -
    xen-kmp-default-4.2.2_04_3.0.76_0.11-0.7.5
    -

    If xen-kmp is not installed, obtain it from the installation ISO and install it first.

    -
    -
    1. Run the following command to open the /etc/sysconfig/kernel file:

      vi etc/sysconfig/kernel

      -
    2. Add the xen-pv and VirtIO drivers after INITRD_MODULES= (the format of drivers depends on the OS).
      SIA10000xxxxx:~ # vi /etc/sysconfig/kernel 
-# (like drivers for scsi-controllers, for lvm or reiserfs)
-#
-INITRD_MODULES="ata_piix ata_generic xen_vnif xen_vbd xen_platform_pci virtio_blk virtio_scsi virtio_net virtio_pci virtio_ring virtio"
      -
    3. Run the mkinitrd command to regenerate initrd:

      If the virtual file system is not the default initramfs or initrd, run the dracut -f Name of the initramfs or initrd file actually used command. The actual initramfs or initrd file name can be obtained from the menu.lst or grub.cfg file (/boot/grub/menu.lst, /boot/grub/grub.cfg, or /boot/grub2/grub.cfg).

      -
      -

      The following is an example initrd file of SUSE 11 SP4:

      -
      default 0
-timeout 10
-gfxmenu (hd0,0)/boot/message
-title sles11sp4_001_[_VMX_]
-root (hd0,0)
-kernel /boot/linux.vmx vga=0x314 splash=silent console=ttyS0,115200n8 console=tty0 net.ifnames=0 NON_PERSISTENT_DEVICE_NAMES=1 showopts
-initrd /boot/initrd.vmx
-title Failsafe_sles11sp4_001_[_VMX_]
-root (hd0,0)
-kernel /boot/linux.vmx vga=0x314 splash=silent ide=nodma apm=off noresume edd=off powersaved=off nohz=off highres=off processsor.max+cstate=1 nomodeset x11failsafe console=ttyS0,115200n8 console=tty0 net.ifnames=0 NON_PERSISTENT_DEVICE_NAMES=1 showopts
-initrd /boot/initrd.vmx
      -

      /boot/initrd.vmx in the initrd line is the initrd file actually used. Run the dracut -f /boot/initrd.vmx command. If the initrd file does not contain the /boot directory, such as /initramfs-xxx, run the dracut -f /boot/initramfs-xxx command.

      -
    4. Run the following commands to check whether the PVOPS module for Xen or VirtIO module for KVM is loaded:

      lsinitrd /boot/initrd-`uname -r` | grep xen

      -
      lsinitrd /boot/initrd-`uname -r` | grep virtio

      If you add built-in drivers to the initrd or initramfs file, the ECS will not be affected. This makes it easy to modify the drivers. However, you cannot check the drivers by running the lsinitrd command. You can run the following commands to check whether built-in drivers are in the kernel:

      -

      cat /boot/config-`uname -r` | grep CONFIG_VIRTIO | grep y

      -

      cat /boot/config-`uname -r` | grep CONFIG_XEN | grep y

      -
      -
    -
  • If the OS version is SUSE 12 SP1, perform the following steps:
    1. Run the following command to open the /etc/dracut.conf file:

      vi /etc/dracut.conf

      -
    2. Press i to enter editing mode and add the xen-pv and VirtIO drivers to add-drivers (the format varies depending on the OS).
      [root@CTU10000xxxxx ~]# vi /etc/dracut.conf 
-# additional kernel modules to the default
-add_drivers+="ata_piix ata_generic xen_vnif xen_vbd xen_platform_pci virtio_blk virtio_scsi virtio_net virtio_pci virtio_ring virtio"
      -
    3. Press Esc, enter :wq, and press Enter. The system saves the change and exits the /etc/dracut.conf file.
    4. Run the following command to regenerate initrd:

      dracut -f /boot/initramfs-File name

      -

      If the virtual file system is not the default initramfs, run the dracut -f Name of the initramfs or initrd file actually used command. The actual initramfs or initrd file name can be obtained from the grub.cfg file, which can be /boot/grub/grub.cfg, /boot/grub2/grub.cfg, or /boot/grub/grub.conf depending on the OS.

      -
    5. If the virtual file system is initramfs, run the following commands to check whether native Xen and KVM drivers have been loaded:

      lsinitrd /boot/initramfs-`uname -r`.img | grep xen

      -

      lsinitrd /boot/initramfs-`uname -r`.img | grep virtio

      -

      If the virtual file system is initrd, run the following commands to check whether native Xen and KVM drivers have been loaded:

      -

      lsinitrd /boot/initrd-`uname -r` | grep xen

      -

      lsinitrd /boot/initrd-`uname -r` | grep virtio

      -
    -
  • If the OS version is later than SUSE 12 SP1 or openSUSE 13, perform the following steps:

    What Do I Do If the Disks of an ECS Created from a CentOS Image Cannot Be Found?

    -

    Symptom

    Generally, this is because the xen-blkfront.ko module is not loaded during the startup. You need to modify OS kernel startup parameters. Figure 1 shows the startup screen after the login to the ECS.

    -
    Figure 1 Startup screen
    -
    -

    Solution

    Perform the following operations to modify OS kernel boot parameters:

    -

    These operations must be performed after the OS starts. You are advised to modify kernel boot parameters in the ECS used for creating the image.

    -
    -
    1. Run the following command to log in to the OS:
      lsinitrd /boot/initramfs-`uname -r`.img |grep -i xen
      • If the command output contains xen-blkfront.ko, contact the customer service.
      • If no command output is displayed, go to 2.
      -
      -
    2. Back up the GRUB configuration file.
      • If the ECS runs CentOS 6, run the following command:

        cp /boot/grub/grub.conf /boot/grub/grub.conf.bak

        -
      • If the ECS runs CentOS 7, run the following command:

        cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.bak

        -
      -
    3. Use the vi editor to open the GRUB configuration file. Run the following command (using CentOS 7 as an example):

      vi /boot/grub2/grub.cfg

      -
    4. Add xen_emul_unplug=all to the default boot kernel.

      Search for the line that contains root=UUID= and add xen_emul_unplug=all to the end of the line.

    Installing the PV Driver

    -

    Scenarios

    When using an ECS or external image file to create a private image, ensure that the PV driver has been installed in the OS to enable Xen virtualization for subsequently created ECSs, improve the I/O processing performance of the ECSs, and implement advanced functions such as monitoring hardware of the ECSs.

    -

    If you do not install the PV driver, the ECS network performance will be poor, and the security group and firewall configured for the ECS will not take effect.

    -
    -

    The PV driver has been installed by default when you use a public image to create ECSs. You can perform the following operations to verify the installation:

    -

    Open the version configuration file to check whether the PV driver is the latest:

    -
    C:\Program Files (x86)\Xen PV Drivers\bin\version
    • If the PV driver version is later than 2.5, you do not need to install the PV driver.
    • If the PV driver version is not displayed or the version is 2.5 or earlier, perform operations in Installing the PV Driver.
    -
    -
    -

    Prerequisites

    • An OS has been installed for the ECS, and an EIP has been bound to the ECS.
    • The remaining capacity of the ECS system disk must be greater than 32 MB.
    • If the ECS uses Windows 2008, you must install the PV driver using the administrator account.
    • The PV driver software package has been downloaded on the ECS. For how to obtain the software package, see Obtaining Required Software Packages.
    • To avoid an installation failure, perform the following operations before starting the installation:
      • Uninstall third-party virtualization platform tools, such as Citrix Xen Tools and VMware Tools. For how to uninstall the tools, see the corresponding official documents of the tools.
      • Disable your antivirus and intrusion detection software. You can enable the software after the PV driver is installed.
      -
    -
    -

    Installing the PV Driver

    1. Log in to the Windows ECS using VNC.

      For details about how to log in to an ECS, see Elastic Cloud Server User Guide.

      -

      You must log in to the ECS using VNC. Remote desktop connection is not allowed because the NIC driver needs to be updated during the installation but the NIC is in use for the remote desktop connection. As a result, the installation will fail.

      -
      -
    2. On the ECS, choose Start > Control Panel.
    3. Click Uninstall a program.
    4. Uninstall GPL PV drivers for Windows x.x.x.xx as prompted.
    5. Download the required PV driver based on the ECS OS and Obtaining Required Software Packages.
    6. Decompress the PV driver software package.
    7. Right-click GPL PV Drivers for Windows x.x.x.xx, select Run as administrator, and complete the installation as prompted.
    8. Restart the ECS as prompted to make the PV driver take effect.

      ECSs running Windows Server 2008 must be restarted twice.

      -

      After the PV driver is installed, the ECS NIC configuration will be lost. If you have configured NICs before, you need to configure them again.

      -
      -
    -
    -

    Verifying the Installation

    Perform the following steps to verify the installation of the PV driver:

    -
    1. Click Start. Choose Control Panel > Programs and Features.
    2. Locate the PV driver for Windows.

      If the PV driver exists, the installation is successful, as shown in Figure 1.

    Uninstalling the PV Driver from a Linux ECS

    -

    Scenarios

    When optimizing a Linux private image, you need to change the UUID in the fstab and GRUB configuration files, and install native Xen and KVM drivers on the ECS. To ensure that you can successfully install native Xen and KVM drivers, you must uninstall the PV driver from the ECS.

    -
    -

    Procedure

    1. Log in to the ECS as user root using VNC.
    2. Run the following command to check whether the PV driver is installed in the OS:

      ps -ef | grep uvp-monitor

      -

      The PV driver is installed in the OS if the following information is displayed:

      -
      root     4561        1    0   Jun29 ?           00:00:00   /usr/bin/uvp-monitor
-root     4567     4561    0   Jun29 ?           00:00:00   /usr/bin/uvp-monitor
-root     6185     6085    0   03:04  pts/2      00:00:00   grep uvp-monitor
      - -
    3. In the VNC login window, open the CLI.

      For how to open the CLI, see the OS manual.

      -
    4. Run the following command to uninstall the PV driver:

      /etc/.uvp-monitor/uninstall

      -
      • The PV driver is uninstalled successfully if the following command output is displayed:
        The PV driver is uninstalled successfully. Reboot the system for the uninstallation to take effect.
        -
      • If .uvp-monitor is not contained in the command output, go to 5.
        -bash: /etc/.uvp-monitor/uninstall: No such file or directory
        -
      -
    5. Perform the following operations to delete uvp-monitor that failed to take effect, preventing log overflow:
      1. Run the following command to check whether UVP user-mode programs are installed in the OS:

        rpm -qa | grep uvp

        -

        Information similar to the following is displayed:

        -
        libxenstore_uvp3_0-3.00-36.1.x86_64
-uvp-monitor-2.2.0.315-3.1.x86_64
-kmod-uvpmod-2.2.0.315-3.1.x86_64
        -
      2. Run the following commands to delete the installation packages:

        rpm -e kmod-uvpmod

        -

        rpm -e uvp-monitor

        -

        rpm -e libxenstore_uvp

    How Do I Install Native Xen and KVM Drivers?

    -

    Scenarios

    When optimizing a Linux private image, you need to install native Xen and KVM drivers for the image.

    -

    If you do not install Xen drivers for the image, the network performance of the ECSs created from this image will be poor, and the security groups and firewall configured for the ECSs will not take effect.

    -

    If you do not install KVM drivers for the image, the NICs of the ECSs may not be detected and the ECSs will be unable to communicate with other resources.

    -
    -
    -

    This section describes how to install native Xen and KVM drivers.

    -

    Prerequisites

    • The kernel version must be later than 2.6.24.
    • Antivirus and intrusion detection software have been disabled. You can enable them after Xen and KVM drivers are installed.
    -
    -

    Procedure

    Modify the configuration file depending on the OS.
    • CentOS, EulerOS

      Take CentOS 7.0 as an example. Modify the /etc/dracut.conf file. Add the xen-pv and VirtIO drivers to add_drivers. xen-pv drivers include xen-blkfront and xen-netfront. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Save and exit the /etc/dracut.conf file. Run the dracut -f command to regenerate initrd.

      -

      For details, see CentOS and EulerOS.

      -
    • Ubuntu and Debian

      Modify the /etc/initramfs-tools/modules file. Add the xen-pv and VirtIO drivers. xen-pv drivers include xen-blkfront and xen-netfront. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Save and exit the /etc/initramfs-tools/modules file. Run the update-initramfs -u command to regenerate initrd.

      -

      For details, see Ubuntu and Debian.

      -
    • SUSE and openSUSE
      • If the OS version is earlier than SUSE 12 SP1 or openSUSE 13, modify the /etc/sysconfig/kernel file and add xen-pv and VirtIO drivers to INITRD_MODULES="". xen-pv drivers include xen_vnif, xen_vbd, and xen_platform_pci. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Run the mkinitrd command to regenerate initrd.
      • If the OS version is SUSE 12 SP1, modify the /etc/dracut.conf file and add xen-pv and VirtIO drivers to add_drivers. xen-pv drivers include xen_vnif, xen_vbd, and xen_platform_pci. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Run the dracut -f command to regenerate initrd.
      • If the OS version is later than SUSE 12 SP1 or openSUSE 13, modify the /etc/dracut.conf file and add xen-pv and VirtIO drivers to add_drivers. xen-pv drivers include xen-blkfront and xen-netfront. VirtIO drivers include virtio_blk, virtio_scsi, virtio_net, virtio_pci, virtio_ring, and virtio. Separate driver names with spaces. Save and exit the /etc/dracut.conf file. Run the dracut -f command to regenerate initrd.
      -
      For details, see SUSE and openSUSE.

      For SUSE, run the following command to check whether xen-kmp (driver package for xen-pv) is installed:

      -

      rpm -qa |grep xen-kmp

      -

      If information similar to the following is displayed, xen-kmp is installed in the OS:

      -
      xen-kmp-default-4.2.2_04_3.0.76_0.11-0.7.5
      -

      If xen-kmp is not installed, obtain it from the ISO file and install it.

      -

      If you add built-in drivers to the initrd or initramfs file by mistake, the ECS will not be affected.

      -
      -
      -
    -
    -
    -

    CentOS and EulerOS

    1. Run the following command to open the /etc/dracut.conf file:

      vi /etc/dracut.conf

      -
    2. Press i to enter editing mode and add the xen-pv and VirtIO drivers to add_drivers (the format varies depending on the OS).
      [root@CTU10000xxxxx ~]# vi /etc/dracut.conf 
-# additional kernel modules to the default 
-add_drivers+="xen-blkfront xen-netfront virtio_blk virtio_scsi virtio_net virtio_pci virtio_ring virtio" 
-......
      -
    3. Press Esc, enter :wq, and press Enter. The system saves the change and exits the /etc/dracut.conf file.
    4. Run the following command to regenerate initrd:

      dracut -f /boot/initramfs-2.6.32-573.8.1.el6.x86_64.img

      -

      If the virtual file system is not the default initramfs, run the dracut -f Name of the initramfs or initrd file actually used command. The actual initramfs or initrd file name can be obtained from the grub.cfg file, which can be /boot/grub/grub.cfg, /boot/grub2/grub.cfg, or /boot/grub/grub.conf depending on the OS.

      -
    5. If the virtual file system is initramfs, run the following commands to check whether native Xen and KVM drivers have been loaded:

      lsinitrd /boot/initramfs-`uname -r`.img | grep xen

      -

      lsinitrd /boot/initramfs-`uname -r`.img | grep virtio

      -

      If the virtual file system is initrd, run the following commands to check whether native Xen and KVM drivers have been loaded:

      -

      lsinitrd /boot/initrd-`uname -r` | grep xen

      -

      lsinitrd /boot/initrd-`uname -r` | grep virtio

      -

      Assume that the virtual file system is initramfs. The following command output will be displayed:

      -

    SUSE and openSUSE

    If the OS version is earlier than SUSE 12 SP1 or openSUSE 13, modify the /etc/sysconfig/kernel file. For details, see scenario 1.

    -

    If the OS version is SUSE 12 SP1, modify the /etc/dracut.conf file and add xen-pv and VirtIO drivers. For details, see scenario 2.

    -
    If the OS version is later than SUSE 12 SP1 or openSUSE 13, modify the /etc/dracut.conf file and add xen-pv and VirtIO drivers to add_drivers. For details, see scenario 3.
    • If the OS version is earlier than SUSE 12 SP1 or openSUSE 13, perform the following steps:

      For SUSE, run the following command to check whether xen-kmp (driver package for xen-pv) is installed in the OS:

      -

      rpm -qa |grep xen-kmp

      -

      If information similar to the following is displayed, xen-kmp is installed:

      -
      xen-kmp-default-4.2.2_04_3.0.76_0.11-0.7.5
      -

      If xen-kmp is not installed, obtain it from the installation ISO and install it first.

      -
      -
      1. Run the following command to open the /etc/sysconfig/kernel file:

        vi etc/sysconfig/kernel

        -
      2. Add the xen-pv and VirtIO drivers after INITRD_MODULES= (the format of drivers depends on the OS).
        SIA10000xxxxx:~ # vi /etc/sysconfig/kernel 
-# (like drivers for scsi-controllers, for lvm or reiserfs)
-#
-INITRD_MODULES="ata_piix ata_generic xen_vnif xen_vbd xen_platform_pci virtio_blk virtio_scsi virtio_net virtio_pci virtio_ring virtio"
        -
      3. Run the mkinitrd command to regenerate initrd:

        If the virtual file system is not the default initramfs or initrd, run the dracut -f Name of the initramfs or initrd file actually used command. The actual initramfs or initrd file name can be obtained from the menu.lst or grub.cfg file (/boot/grub/menu.lst, /boot/grub/grub.cfg, or /boot/grub2/grub.cfg).

        -
        -

        The following is an example initrd file of SUSE 11 SP4:

        -
        default 0
-timeout 10
-gfxmenu (hd0,0)/boot/message
-title sles11sp4_001_[_VMX_]
-root (hd0,0)
-kernel /boot/linux.vmx vga=0x314 splash=silent console=ttyS0,115200n8 console=tty0 net.ifnames=0 NON_PERSISTENT_DEVICE_NAMES=1 showopts
-initrd /boot/initrd.vmx

-initrd /boot/initrd.vmx
        -

        /boot/initrd.vmx in the initrd line is the initrd file actually used. Run the dracut -f /boot/initrd.vmx command. If the initrd file does not contain the /boot directory, such as /initramfs-xxx, run the dracut -f /boot/initramfs-xxx command.

        -
      4. Run the following commands to check whether the PVOPS module for Xen or VirtIO module for KVM is loaded:

        lsinitrd /boot/initrd-`uname -r` | grep xen

        -
        lsinitrd /boot/initrd-`uname -r` | grep virtio

      5. Restart the ECS.
      6. Modify the /boot/grub/menu.lst file. Add xen_platform_pci.dev_unplug=all and modify the root configuration.

        Before the modification:

        -

        • For SUSE 11 SP1 64bit to SUSE 11 SP4 64bit, add xen_platform_pci.dev_unplug=all to the menu.lst file. For SUSE 12 or later, this function is enabled by default, and you do not need to configure it.
        -
        -
      7. Run the following commands to check whether the Xen drivers exist in initrd:

        lsinitrd /boot/initrd-`uname -r` | grep xen

        If the virtual file system is not the default initramfs, run the dracut -f Name of the initramfs or initrd file actually used command. The actual initramfs or initrd file name can be obtained from the grub.cfg file, which can be /boot/grub/grub.cfg, /boot/grub2/grub.cfg, or /boot/grub/grub.conf depending on the OS.

        -
      5. If the virtual file system is initramfs, run the following commands to check whether native Xen and KVM drivers have been loaded:

        lsinitrd /boot/initramfs-`uname -r`.img | grep xen

        -

        lsinitrd /boot/initramfs-`uname -r`.img | grep virtio

        -

        If the virtual file system is initrd, run the following commands to check whether native Xen and KVM drivers have been loaded:

        -

        lsinitrd /boot/initrd-`uname -r` | grep xen

        -

        lsinitrd /boot/initrd-`uname -r` | grep virtio

        -
      -
    • If the OS version is later than SUSE 12 SP1 or openSUSE 13, perform the following steps:
      Take SUSE Linux Enterprise Server 12 SP2 (x86_64) as an example.
      1. Run the following command to open the /etc/dracut.conf file:

        vi /etc/dracut.conf

        -
      2. Press i to enter editing mode and add the xen-pv and VirtIO drivers to add_drivers (the format varies depending on the OS).
        [root@CTU10000xxxxx ~]# vi /etc/dracut.conf 
-# additional kernel modules to the default
-add_drivers+="ata_piix ata_generic xen-blkfront xen-netfront virtio_blk virtio_scsi virtio_net virtio_pci virtio_ring virtio"
        -
      3. Press Esc, enter :wq, and press Enter. The system saves the change and exits the /etc/dracut.conf file.
      4. Run the following command to regenerate initrd:

        dracut -f /boot/initramfs-File name

        -

        If the virtual file system is not the default initramfs, run the dracut -f Name of the initramfs or initrd file actually used command. The actual initramfs or initrd file name can be obtained from the grub.cfg file, which can be /boot/grub/grub.cfg, /boot/grub2/grub.cfg, or /boot/grub/grub.conf depending on the OS.

        -
      5. If the virtual file system is initramfs, run the following commands to check whether native Xen and KVM drivers have been loaded:

        lsinitrd /boot/initramfs-`uname -r`.img | grep xen

        -

        lsinitrd /boot/initramfs-`uname -r`.img | grep virtio

        -

        If the virtual file system is initrd, run the following commands to check whether the native Xen and KVM driver modules are successfully loaded:

        -

        lsinitrd /boot/initrd-`uname -r` | grep xen

        -

        lsinitrd /boot/initrd-`uname -r` | grep virtio

        -

        Assume that the virtual file system is initrd. The following command output will be displayed:

        If you add built-in drivers to the initrd or initramfs file, the ECS will not be affected. This makes it easy to modify the drivers. However, you cannot check the drivers by running the lsinitrd command. You can run the following commands to check whether built-in drivers are in the kernel:

        -

        cat /boot/config-`uname -r` | grep CONFIG_VIRTIO | grep y

    Permissions

    +

    +

    If you need to grant different permissions to employees in your enterprise to access your IMS resources, IAM is a good choice for fine-grained permissions management. IAM provides identity authentication, permissions management, and access control, helping you secure access to your resources.

    +

    With IAM, you can use your account to create IAM users for your employees, and grant permissions to the users to control their access to specific resource types. For example, some software developers in your enterprise need to use IMS resources but must not delete them or perform any high-risk operations. To achieve this result, you can create IAM users for the software developers and grant them only the permissions required for using IMS resources.

    +

    If your account does not require individual IAM users for permissions management, skip this section.

    +

    IAM can be used free of charge. You pay only for the resources in your account. For more information about IAM, see IAM Service Overview.

    +

    +

    IMS Permissions

    By default, new IAM users do not have any permissions assigned. You need to add a user to one or more groups, and assign policies or roles to these groups. The user then inherits permissions from the groups it is a member of. This process is called authorization. After authorization, the user can perform specified operations on cloud services based on the permissions.

    +

    IMS is a project-level service deployed and accessed in specific physical regions. When you grant IMS permissions to a user group, set Scope to Region-specific projects and then select projects for the permissions to take effect. If you select All projects, the permissions will take effect for the user group in all region-specific projects. Before you access IMS, switch to a region where you have been authorized to use IMS.

    +

    You can grant user permissions by using roles and policies.

    +
    • Roles: A type of coarse-grained authorization mechanism that defines permissions related to user responsibilities. This mechanism provides only a limited number of service-level roles for authorization. When using roles to grant permissions, you need to also assign other roles on which the permissions depend to take effect. However, roles are not an ideal choice for fine-grained authorization and secure access control. +

      +
      +
    • Policies (recommended): A type of fine-grained authorization mechanism that defines permissions required to perform operations on specific cloud resources under certain conditions. This mechanism allows for more flexible policy-based authorization, meeting requirements for secure access control. For example, you can grant IMS users only the permissions for managing a certain type of image resources.

      Most policies define permissions based on APIs. For the API actions supported by IMS, see "Permission Policies and Supported Actions" in Elastic Cloud Server API Reference.

    Creating a User and Granting Permissions

    +

    Scenarios

    This section describes how to use Identity and Access Management (IAM) to implement fine-grained permissions control for your IMS resources. With IAM, you can:

    +
    • Create IAM users for employees based on the organizational structure of your enterprise. Each IAM user has their own security credentials, providing access to IMS resources.
    • Grant only the permissions required for users to perform a task.
    • Entrust an account or cloud service to perform professional and efficient O&M on your IMS resources.
    +

    If your account does not need individual IAM users for permissions management, you can skip this section.

    +

    This section uses the IMS ReadOnlyAccess permission as an example to describe how to grant permissions to a user. Figure 1 shows the process.

    +
    +

    Prerequisites

    Learn about the permissions (see IMS Permissions) supported by IMS. For the system permissions of other services, see Permissions.

    +
    +

    Process Flow

    Figure 1 Process for granting IMS permissions
    +
    1. Create a user group and assign permissions.

      Create a user group on the IAM console, and grant the read-only permission to the group by assigning the IMS ReadOnlyAccess permission.

      +
    2. Create an IAM user and add it to the user group.

      Create a user on the IAM console and add the user to the group created in 1.

      +
    3. Log in and verify permissions.

      Log in to the management console using the IAM user, switch to a region where the permissions take effect, and verify the permissions (assume that the user has only the IMS ReadOnlyAccess permission).

      +
      • In the Service List, choose Image Management Service. On the IMS console, perform operations except querying images, such as creating, modifying, and deleting an image.

        For example, click Create Private Image in the upper right corner. If you are prompted insufficient permissions, the IMS ReadOnlyAccess permission has taken effect.

        +
      • Choose any other service in the Service List, such as Virtual Private Cloud. If a message appears indicating insufficient permissions to access the service, the IMS ReadOnlyAccess permission has taken effect.

    Creating a Custom Policy

    +

    Scenarios

    Custom policies can be created as a supplement to the system permissions of IMS. For the actions supported for custom policies, see "Permissions Policies and Supported Actions" in Image Management Service API Reference.

    +

    You can create custom policies in either of the following two ways:

    +
    • Visual editor: Select cloud services, actions, resources, and request conditions without the need to know policy syntax.
    • JSON: Edit JSON policies from scratch or based on an existing policy.
    +

    For details, see "Creating a Custom Policy" in Identity and Access Management User Guide. This section provides examples of common IMS custom policies.

    +
    +

    Example Policies

    • Example 1: Allowing users to create images
      {
+    "Version": "1.1",
+    "Statement": [
+        {
+            "Effect": "Allow",
+            "Action": [
+                "ims:serverImages:create",
+                "obs:bucket:*",
+                "obs:object:*",
+                "kms:*:*",
+                "ecs:cloudServers:get",
+                "ecs:servers:get",
+                "ecs:serverVolumes:use",
+                "ecs:cloudServers:list",
+                "ecs:serverVolumeAttachments:list",
+                "ecs:servers:list",
+                "evs:volumes:*",
+                "bms:servers:list",
+                "bms:servers:get",
+                "bms:serverFlavors:get"
+            ]
+        }
+    ]
+}
      +

      The action required for creating an image is ims:serverImages:create. Others are dependent actions for creating an image.

      +
      +
    • Example 2: Denying image deletion

      A deny policy must be used in conjunction with other policies to take effect. If the policies assigned to a user contain both Allow and Deny actions, the Deny actions take precedence over the Allow actions.

      +

      The following method can be used if you need to assign the IMS FullAccess policy to a user but also forbid the user from deleting images. Create a custom policy for denying image deletion, and assign both the policies to the group the user belongs to. Then, the user can perform all operations on IMS except deleting images. The following is an example deny policy:

      +
      {
+    "Version": "1.1",
+    "Statement": [
+        {
+            "Effect": "Deny",
+            "Action": [
+                "ims:images:delete"
+            ]
+        }
+    ]
+}
