It would be nice if you can post some short informations of how you did it.
Especially your hardware configuration, Vt-d enabled board, Processor, RAM, ... But also which Distribution and Xen version.
I had tought about the same but have a time and money problem
At the moment 2 Servers gets dusty here, one fore MP, one for Router/NAS/others.
The second server is already virtualized with Vmware. Xen gave me headache because of the Software installation
