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 ?
