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:

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:

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?
