No magic here I'm afraid, just plain science :)

Here's for Ubuntu 9.04 Server amd4 without LVM:
Part 1: Installing HVM domU : http://pastebin.com/f630547c
Part 2: Converting HVM to PV, using Lenny's Xen kernel :
http://pastebin.com/f63285128

Here's the same thing for RHEL/Centos 5 that I created some time ago:
Part 1. Creating a Centos HVM domU with working PV drivers :
http://pastebin.com/fb6fe631
Part 2, converting HVM guest to PV guest : http://pastebin.com/f6a5022bf

Using LVM for "/" on domU makes thing somewhat complicated. For
example, on Ubuntu install /boot will be located on the end of disk in
an extended partition, which makes in unreadable by pygrub. There's a
workaround for this, but the easiest way is to NOT use LVM for "/"
when installing.

Regards,

Fajar
