Well, apparently the Karmic's kernel that have support for running as Xen pv domU is the -generic version...

While it may not explicitly support Xen domU, it runs just fine. That
is, assuming your dom0 (Xen and hardware/BIOS) supports running pv_ops
kernel.

Generally it's pretty much the same thing that would happen if you do
a distro-upgrade to newer version. Some things to watch out though:
- Karmic's upstart uses /etc/init/, which is different from previous versions
- if you use Karmic's (or any pv_ops) kernel, xen console will be on
hvc0, so you should adjust your system (/etc/init/*, /etc/securetty)
to spawn login screen there
- with pv_ops kernel, disks will be mapped as xvda (and not sda/hda).
You may need to change domU config, fstab, and grub.conf manually to
match that.

Fajar
