You might want to look at the talk I gave at this year's workshop:
"Xen as a test environment"
Xen-side I have had fairly good stability, although that has
been with Intel hardware running NetBSD. I did some rough
testing of stuff running Linux for the talk, and it seemed to
work fine. My home cell runs all on Xen-hosted domains and
seems to run well, but it is fairly low use (about a dozen
users, with me being the only real load on afs).
I would keep a close eye on your i/o systems throughput, and
how well that works when you add additional stuff on to a
particular machine. For me, the bottleneck seems to be disk
i/o. As a previous poster mentioned, you can migrate things
slowly, ramping up the load on a system until you've found
the level you want.
Modulo sizing the load on your system properly, AFS and Xen
seem to co-exist very well, at least for me.
