I think the real answer for the long term is a boot loader inside domU.
Porting GRUB, for example, would make the kernel loading as easy as it
is on non-virtual machines, and could also allow extra options to be
passed in from the domain builder in dom0.  I would like to do that, but
don't have any time at the moment to work on it.

As an intermediate measure, domUloader gives more functionality, because
it can understand more filesystems (are many people using FS other than
reiser and ext2/3?).  I would prefer not to involve dom0's kernel in
things, though; if nothing else it becomes another thing tying dom0 to
