xen also needs custom grub configs, since you don't boot the linux kernel,
you boot the xen hypervisor which in turns runs a privileged "guest" OS
kernel as the thing the users interact with to run the other "guests".  (In
xen parlance "guests" are called "domains", and there is no real "host",
just the hypervisor.)
