It certainly makes sense to put the PRI handling on a separate server.
The PRI handling is quite time sensitive, so it makes sense to keep it
on a less loaded server.

I don't know whether it makes sense to use Xen for the IP-only servers
though. Xen has traditionally been bad for latency, and even IP-only
servers need to handle requests with reasonably low latency. We have
had good luck with Linux-Vserver and OpenVZ -- one of those may be
able to provide you with the features you require. The advantage is
that they use one kernel for both host and guests, so the latency
should be no worse than it is for a physical server.
