Yes it does.  64-bit 6.3 and 7.0 both run in Xen 3.2 HVMs -- if you
use AMD CPUs.  There's a bunch of niggles in the Intel CPU
virtualisation implementation that cause FreeBSD guests to crash/not
work.  Supposedly, these are fixed in Xen 3.2.1.  However, we don't
use Intel CPUs, so we've never been bitten by these issues.

If you search the -stable and -current mailing lists, I posted the
config files I used to get FreeBSD 6.3 and 7.0 running in Xen 3.2 HVMs
on Debian (using the kernel from Ubuntu).

However, if you want things to be simple, stop using Xen and stick to
KVM, especially with KVM-70 and Linux Kernel 2.6.24.
