Also, we are getting new=20 servers and have the one time oppurtinity to do a switch to another=20 virtualization platform. Right now, We are using GlusterFS underneath the oVirt Cluster and would = like to use it on Proxmox as well. It will be a 3 node cluster. My question to you all is: Has anyone on this list done a migration=20 process from oVirt to Proxmox? Both systems are based on KVM, so a=20 migration should not be that complicated. My main idea is the following: - Set up a Proxmox cluster with 3 nodes - Set up the Gluster storage on the new servers - Create VMs with the same name and copy the raw disk image from the old = Gluster to the new one - Set the copied Raw disk image as bootfile for the created VM - Repeat the step for all VMs, one at a time Since we do not have thousands of VMs we can do this manually, so no=20 need to set up a complicated migration pipeline. The main advantage of=20 this is, that we can migrate a VM one at a time and not all at once. What are your thoughts on this? Will we get trouble with, for example,=20 the drivers inside the VM?
