  • Make sure that the virtual machine that needs to be migrated to the KVM hypervisor has access to the YUM repository in order to download a non-Xen kernel and some other stuff.

  • Once you confirm the preceding options, you can start converting your Xen virtual machines using the following commands.

The following are the different targets to which a Xen VM can be converted:

  • To convert a Xen virtual machine to a KVM standalone host, run the following command:
    # virt-v2v -ic 'xen+ssh://root@xen.example.com' rhel5-1-xen' -o local -os /v2vconvert/ -on rhel5-1-kvm
