When I saw the thread about virtualization a few weeks, I got really excited about Xen and the PCI pass through feature (I was planning to use a Sangoma T1/PRI card). So, in my ignorance, I put together a Citrix XenServer and installed asterisk 1.6.2.6 on a virtual machine. To my disappointment, I learned that XenServer doesn't support PCI pass through. Also, the asterisk is performing poorly, especially the conference bridge that I am running on it (not a heavily used bridge, something like 5-10 connections once or twice a day). For the PSTN connectivity I was using a Cisco 2811 router instead of the Sangoma card.
For the conference to work you need to install a modified real time kernel driver for asterisk to convert 8192 hz to 8000 hz...
I've never used XenServer but I have used Xen to build a firewall etc and it worked very well, and I run a lot of asterisk systems on Xen and haven't had any problems.
