Hello, You can do 'virsh pool-create' on the same directory as your currently running Xen VMs' disks. That will make the disks visible to libvirt (prerequisite for them to be exportable to oVirt).
If libvirt doesn't see your stopped VMs when doing 'virsh list --all' you need to add the <UUID> parameter to their definition file - For that, as explain, first have your vm running, then do 'virsh dumpxml vmname' You will see something like <domain type='xen' id='10'> <name>vmname</name> <uuid>7ecf52a5-3657-fc7a-b2e2-66edd4cf1b6c</uuid> - Then, shutdown your vm and copy the UUID from the dump you just did in your vm definition file : In /etc/xen/vmname put the missing line with the following format: uuid = "7ecf52a5-3657-fc7a-b2e2-66edd4cf1b6c" The vm should now be visible by libvirt when doing 'virsh list --all' Guillaume Pavese Ingénieur Système et Réseau Interactiv-Group On Sun, May 2, 2021 at 6:47 PM IT (Hema Arun) <[email protected]> wrote: > Hi Guillaume, > > > > Thank you for the reply back.
