To me it's broken that the domU kernel isn't taken from /netbsd in the
domU filesystem.

When i update a machine, I update kernel and user, and it would be good
for a domU to be able to do this in one operation without dom0 access,
just like a real machine.

So, I'd like to see 'xm start' be able to mount the domU vnd from a file
read-only, grab the kernel, unmount, and then boot with the kernel file
and the vnds configured normally.  But I have not liked this enough to
actually do it :-)

So I think you're right about the benefits being having the real and
reference kernel being the same, and not having to update twice, but I
think that's pretty important.
