Yes, you'll just need to do some initrd hacking if you want to have them
boot, login to their targets and mount a root file system on LUN. There
are some programs out there which take a lot of the manual surgery out
of this, though I can't think of their names off hand.

The fastest route to this is to put dom-0's root file system on
something that can be exported via nfs. Since nfs is already supported
by the kernel you won't have to change the initrd, just the boot
options.

What I highly recommend is having a small, local disk that dom-0 and
guests can use for swap.
