Out of interest was that just the kernel or did you carry on and
convert some/all of user land as well?

Sorry, I don't recall which VM we are talking about here but as it's
64-bit it's good. If it's running under PVH mode that's best. Check
that with:

$ cat /sys/hypervisor/guest_type

If it doesn't say PVH then you might like to try that out at some
point with:

xen shell> virtmode pvh

Should work as long as you are also using grub2 (/boot/grub/grub.cfg
exists). If for some reason it doesn't work you can revert back to
what you had with:

xen shell> virtmode pv

All new VMs have been amd64/PVH for a bit over a year now.

Cheers,
Andy
