Hello,

we would like to migrate our oVirt Cluster to Proxmox, because of the 
recent events regarding RedHat and CentOS. Also, we are getting new 
servers and have the one time oppurtinity to do a switch to another 
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 
process from oVirt to Proxmox? Both systems are based on KVM, so a 
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 
need to set up a complicated migration pipeline. The main advantage of 
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, 
the drivers inside the VM?

Thank you in advance and many greetings from Cologne,

Marc Sauer
