[CentOS] Xen stack scheme

I need to restructure my server farm from tower PC:s to a minimal amount 
of 1U rack servers. I am going to rely on xen virtualization, as KVM 
seems not to be very mature yet.

My current problem is the mail server, which uses a lot of CPU and I/O. 
A dedicated machine would be the best option. But would there be any 
sense in this:

- run the mail server in xen dom0 (to get full native performance)
- append a couple of light-weight servers as domU:s (like name server)
