Finally I have the Ubuntu Karmic running as PV machine under my open source Xen and XenServer 5.5...
There is only one kernel package with support for Xen (CONFIG_XEN=y), and it is: "linux-ec2".
So, I have read this guide: http://community.citrix.com/display/ocb/2008/07/02/Installing+Ubuntu+on+XenServer;jsessionid=C126EB0931801626CB857A098C195EAE
And before convert my VM from HVM to PVM, I install the right kernel with:
aptitude install linux-ec2 grub
update-grub
vim /boot/grub/menu.lst (to change uuid to root (hd0,0))...
Cheers!
Thiago

Well, apparently the Karmic's kernel that have support for running as Xen pv domU is the -generic version... 2009/11/18 Fajar A. Nugraha <fajar@xxxxxxxxx>

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.
