It's not entirely true that an OS has to have support for Xen to run
under it. It's true for paravirtualized guests. However, if your
hardware has VT-x support Xen can do full virtualization. It's not as
fast as paravirtualization, but I'm successfully using it on one
system to run an unmodified Windows XP installation as a guest OS.
What's unique about VirtualBox is it can do full virtualization on old
hardware that doesn't have VT-x support.
