>From the networking point of view, it's more or less the same situation as in real physical network - depends on the network segments, firewalling etc.
Main difference is, that ale these virtual machines share common computing power, so there's "new" room to "unwanted" computing power consumption from the compromised DomU, that may affect other DomUs and tasks assigned to them (the degree depends on configs of vcpus, schedulers etc.) and logically virtual machines are more vulnerable to DOS attacks.

If a DomU was compramised, could the Dom0 or other DomUs be compramised?

I guess I'm trying to work out how much isolated Xen gives..

Thanks
