Xen's only real competition to date is EMC VMWare ESX (that expensive
hypervisor, not the giveaway version) - the other hypervisor based
product for x86/64 systems.
As of May 2006 announcements, MS is supposed to release a
hypervisor-based system 6 months after Stinkhorn Server is RTM
So, that (may) take care of the low-level performance issues which
separate MSVS2005 from the likes of VMWare and Xen. Now if Xen can do
some more catchup with VMWare (it must in the management interface at
the very least), and if MS releases anything like the comedic
management interface it had for MSVS, then Xen is still sitting pretty.
