And the plan was the same + i had a convert image step that you do not need. drivers can be an issue if the OS on the VM is windows. read the xml config on ovirt and replicate accordingly on proxmox to avoid any issues. this is probably only an issue on the first VM, i assume the rest would be identical, once you get the right config. I also did one rsync of image while vm was running + another rsync while vm was stopped to have shorter downtime. depends on your network speed vs storage speed if this is sane or not. good luck Ronny
