Hi, >> My question is, how close to the dom0 servers need to be to run a >> domU on either? >> Do they need to be the same hardware type.. etc etc etc?
Nope, because the dom0 provides a nice hardware abstraction layer.
this can be very wrong if you want to use (live)-migration!If you just want to start a VM, shutdown it later and restart it on the other server, the two machines can be different. But if you want to use such cool things like live-migration for s.th. like loadbalancing or maintanance between two servers they should be the same as possible. That doesn't mean that the destination-server could not have faster/more CPU or more RAM, but the CPU and possibly also the chipset should be the same family! Otherwise it can happen during live-migration that on the source-system the CPU is in a status that is not compatible with the destination-system and the VM will crash.
