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
That is the exact process I used when moving from Proxmox to straight
KVM and virt-manager. It's a safe way to move. If a single VM has
issues, you can fall back to the original and figure out what went wrong
without long downtimes. I moved thirty VM's using this process.
I did have issues with Windows machines, and had to manually copy the
machine's GUID to the new virtual machine in order to keep Windows
activated.
