Personally, my answer is: Neither. ;)
I like kvm ( http://kvm.qumranet.com/kvmwiki ).
It seems to be pretty fast and stable and they are working on getting
it caught up on all the xen/vmware features. Downside is that you must
have a newer cpu that can do hardware virt.
Xen and Vmware both have problems that make me never want to use either
of them if I can avoid it. ;)

I don't know off hand of any setup to do that, but I don't see why it
wouldn't be possible with some creative dd usage to get things in the
Several other things to look at:
- libvirt is what I use here on my F8 laptop to
manage virtuals. http://libvirt.org/
It's an abstraction layer over xen/kvm/qemu. It's very nice IMHO.
There's a nice management gui, new virtual setup wizard thing, and a
very very full featured command line client.
- http://virt.kernelnewbies.org/ has some good info on the various tech
out there and how it works. Nice basic background.
