Hi Robbie,
I had this exact same problem, tried for 5-10 hours to fix but never got
Xen Dom working with LVM.
Try installing Centos on a standard partition rather than the default
LVM scheme, it fixed it for me. You can still use LVM partitions for
your VMs with this setup.

Try the same results with 3.4.1 and not 3.4-testing.
Lots of people use centos with no issues.
Below is my grub config for debian 5.0
title Xen 3.4.1 / Debian GNU/Linux, kernel 2.6.18.8-xen
root (hd2,0)
kernel /boot/xen-3.4.1.gz
module /boot/vmlinuz-2.6.18.8-xen root=/dev/sdc1 ro
console=tty0
max_loop=64 #for some reason this lines raps. It should be just after
console=tty on the same line.
module /boot/initrd.img-2.6.18.8-xen

couldnotfind filesystem /dev/root/)
Hi,
I started everything from scratch...
1. Installed CentOS 5.3
2. Installed XEN 3.4-testing as per README
The same problem during the reboot. I copied the Grub entry from the
Native CentOS5.3 installation.
This time am seeing an error additional error :
"Volume group : "VolGroup00" not Found"
Searching the forums, I understand that this is a Logical Volume and
There are a few problems with Logical Volumes. But none of the
workarounds
Seems to work.
I get a feeling that the "mkinitrd" is not doing its job completely.
(or) what am I missing ?
Can someone help me please ?
