 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'

           Kernel panic - not syncing: Attempted to kill init!

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

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? Of course, I plan to 
ask in the fedora-xen mailing list too, but for some weird reason, I am not 
getting their confirmation email.

 Thanks in advance.
