Keep in mind that unless you are exporting hardware ethernet cards to DomU, you will have a significant network performance issue inside a DomU (tech details here http://www.cs.aau.dk/~kleist/Courses/nds-e05/presentations/2609-preformance_overheads_xen.pdf#search=%22xen%20network%20performance%22) but if you run in Dom0 and busy up the CPU, all VMs will suffer. I would run in DomU with an exported PCI NIC instead of using virtual devices.

I second that observation! :)
