I read yeasterday that Windows Server 2008 with Hyper-V is able to run XEN PV domU Linux on it. It probably is also able to run other Xen domU guests, but probably nobody was trying to do so. I do not know details, but it was what I read about Hyper-V hypervisor on Wikipedia. In fact it looks like independent implementation of Xen compatible hypervisor (it uses same hypercall api, but I do not know with which version of Xen it is compatible) with Windows as dom0. Not that anybody would want to run it, but just saying. -- Witold Baryluk
