Hi,

I have been using Xenserver for a long time and I currently have a broken 2 node Xenserver 7 pool backed by Ceph RBD (love my Ceph cluster). Xenserver just will not work well with RBD as it's backend and Citrix's lack of Ceph support has exhausted me... I want to move over to using Proxmox VE.

I know that I will have to go through the process of converting xva to qcow2, but I am wondering what the best route to go using my existing Ceph cluster. I have one Pool with several rbd images for my Xenserver VM's, should I create a new Pool for Proxmox and then delete the old pool when I have migrated everything off? Also, I was wondering if anyone else has made this transition and could offer some tips or advise?

Thanks in advance!
 
Hi,

I never done this, but if you use rbd on Citrix it should be compatible with kvm.
rbd is always the same.
I would make a snapshot and try to use the images directly with kvm.
 
If I recall correct xen uses a kernel outside of the disk image so ensure to install grub and the kernel inside the image before conversion.
 
Thanks for your replies! After sleeping on it, I think I am just going to try for application level migration since most of my VM's are on the latest CentOS 7, seems like it will be the more seamless transition.
