I guess I should of read the the Xen FAQ's
1.4. Does Xen support Microsoft Windows?
The paravirtualized approach we use to get such high performance has not
been usable directly for Windows to date. However Xen 3.0 added Intel
VT-x <http://wiki.xensource.com/xenwiki/IntelVT> support to enable the
running of unmodified guest operating systems, including Windows XP &
2003 Server, using hardware virtualization technology. We are working on
implementing support for the equivalent AMD Pacifica technology.

OpenVZ sounds interesting, and might be a future testing \ learning
endeavor.But for now, I just want to stop the restarts!
