If you need performance best suggestion is get a copy of XenEnterprise and try that. Xen benchmarks say it is as good and maybe better than VI3, although because of VMware's EULA they don't state that directly. I haven't done much testing with the newer 3.0.x versions myself recently, so I can't give any clear indications. However I think the domU to domU interaction is much better. Some of the previous issues where caused by tcp checksum off-loading bugs. Also the new schedule probably helps prevent running out of cpu splices when pushing disk IO.

I'm looking to do something similar, and finally move away from real iron to xen as well, but was curious what the speeds were like over the virtual networks; I'm used to gigabit speeds for transferring files, etc. What are your experiences as far as speeds of transferring files between dom0 and domU's? Thanks so much! Hey there, good story!
