XenServer

  1. Before configuring the yum source on the VM, back up files in the /etc/yum.repos.d directory. Perform the following operations to back up the default source:
    1. Open the directory and run the cd /etc/yum.repos.d command.
    2. Run the ll -h command to check the repo files in the directory.

      If no repo file exists, no further action is required.

    3. Run the mv /etc/yum.repos.d/xxx.repo /etc/yum.repos.d/xxx.repo.backup command to back up all repo files.

      xxx is a file name.

  2. Run the following command to copy the yum source to the /etc/yum.repos.d directory:

    wget -O /etc/yum.repos.d/CentOS7.repo Image source address

    Alternatively, run the following command:

    curl -o /etc/yum.repos.d/CentOS7.repo Image source address

  3. Run yum repolist command to update the yum repository.

    The access may fail (for example, "404 Not Found" is displayed).

    If this problem occurs, use the vi or vim editor to change the value of $releasever following baseurl to 7 in the /etc/yum.repos.d/CentOS7.repo file .

    Run the yum repolist command again to update the yum repository.

  4. Run the following command to install Cloud-Init:

    yum install cloud-init

  5. Run the following command to check the Cloud-Init version:

    cloud-init -v

    If the Cloud-Init version is displayed, the installation is successful.
