Xenserver With Ceph to Proxmox

[flowjo-mj]

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.

If your vm's are linux based then you only need to install grub and the kernel from the package repository and that's it.

Wait, so I don't need to convert the VM images first? Nevermind, didn't mean to post this:
