I'm pretty sure that my Dell GX755 has VT-d I know it at least has some
Virtual IO settings.
Here we go the xensource site has more info:
XENsource lists the following Desktops as having VT-d:
HP Compaq: DC7800<http://h10010.www1.hp.com/wwpc/us/en/en/WF04a/12454-12454-64287-321860-3328898.html>
Truthfully running virtual machines on a Dell Latitude D630 laptop without
VT-D and running them on a GX755 desktop with the VT-D. I honestly haven't
seen any performance gains from the VT-d IO stuff. I think the you will
only see a performance gain if your are running very IO intensive
applications like perhaps a database.
