if you have not built a separate domU kernel then I guess you can still
use the dom0 kernel. At least that worked for me.
 
 
Right. You can use the dom0 kernel.
 
 
 That came as a surprise to me, so I tried it, but with no luck. My Dom0 
f8-xen kernel requires an initrd, so I changed the jailtime:
kernel = "/boot/vmlinuz-2.6-xen"
to:
kernel  = "/boot/vmlinuz-2.6.21-2952.fc8xen"
ramdisk = "/boot/initrd-2.6.21-2952.fc8xen.img"
I can't boot with or without the ramdisk line. With the ramdisk line, I get:
 
Scanning logical volumes
  Reading all physical volumes.  This may take a while...
  No volume groups found
Activating logical volumes
  Volume group "VolGroup00" not found
Creating root device.
Mounting root filesystem.
mount: could not find filesystem '/dev/root'
 
 
 I don't understand why it's saying "no volume groups found", but when 
would it ever work to use a Dom0 initrd for a DomU boot? My Dom0 is on 
LVM, and fstab looks like this:
 
/dev/VolGroup00/LogVol01 /      ext3    defaults        1 1
...
/dev/VolGroup00/LogVol00 swap   swap    defaults        0 0
 
 
And the jailtime fstab looks like this:
 
/dev/sda1   /        ext3      defaults,errors=remount-ro    0     0
/dev/sda2   none     swap      sw                            0     0
proc        /proc    proc      defaults                      0     0
 
 
 So surely, at the very least, initrd has to be rebuilt for the jailtime 
image. Or have I missed something?
Thanks -
Evan
