Pvgrub is pretty great if the DomUs are operated by people that don't
have root on the dom0.  With pvgrub, it's pretty easy to set things
up so that the person that controls the DomU can never mess up the 
DomU to the point that they can't boot[1], something that requires 
a xm config file edit otherwise.

The big downside to pvgrub is that it wants a ext2/3 filesystem and
a grub1 format menu.lst file.
