Thanks Somnath and Christian, Yes, it looks like the latest version of XenServer still runs on an old kernel (3.10). I know the method Christian linked, but it doesn’t work if XenServer is installed from iso. It is really annoying there has been no movement on this for 3 years… I really like XenServer and am excited to use Ceph, I want this to work.
Since there are no VM’s on it yet, I think I will upgrade the kernel and see what happens.
