[Xen-devel] Re: Install paravirtualized drivers after booting forhigh-performance IO

Where is get  a reference to the Windows support using Vanderpool Technology 
Who is doing that Windows support using Vanderpool Technology ?

If Xen can run unmodified Linux , then Xen can run unmodified Windows also ,
