RE: [Xen-users] bare metal xen hypervisor

The Dom0 has direct access to hardware, so in general IO operations should be 
faster (better latency). DomUs access to hardware is provided by hypervisor 
using Dom0 - so the bits have "longer" way to roam out of the VM to real

ThatÂs a new information for me.

Does that mean that the performance of processes in Dom0 ist not better or 
worse than those in any DomU?

I thought that Dom0 processes have a better latency and general performance 
compares to those in a DomU.
