[Fedora-xen] DomU boot on Fedora 6 fails with 'no root found' error.

[Ligesh]

 I am trying to get Xen running on Fedora 6, which I thought would be easy, but I guess not. I am using the standard image from jailtime.org and my domU configuration file is below. I am using the same kernel of the host itself.

------------
 kernel     = '/boot/vmlinuz-2.6.19-1.2895.fc6xen'
 ramdisk    = '/boot/initrd-2.6.19-1.2895.fc6xen.img'
 memory     = 512
 name       = 'test.vm'
 vif        = ['vifname=vif-test0,  mac=aa:00:f6:f4:06:1a']
 vnc        = 0
 vncviewer  = 0
 serial     = 'pty'
 disk       = ['file:/home/test.vm//root.img,sda1,w', 'file:/home/test.vm//vm.swap,sda2,w']
 root = '/dev/sda1 ro'

--------------------------

The above is the error I got. It seems the initrd is searching for volGroup00, which is how the '/' of the HOST is mounted, but I have explicitly given 'root =' in the config file. So I am confused.  Is there anyone here who has experienced this beforehand?

 Thanks in advance.
