It works great, we're using a bunch of these at work (although I haven't set any of them up, just done mostly the followup within a virtual server)... instead of hosting a demo per piece of hardware, we're buying slightly better boxen and getting multiple demos per physical box. If you use the same hardware (and, er, dom0 kernel) you can shuffle xen instances around pretty nicely... we're running heavyweight servers in xen, with good success (java tomcat with thousands of class files, and mysql). IIRC, linux is the only OS supported so far in the xen instances, which may change in the future, but you can roll your own kernel so long as there is xen support in it.
Something I've thought about recently, is setting up a nice beefy home box with many distro's, each on a xen instance... this way I can run more than one at a time if desired, and don't ever have to reboot the physical hardware :) This would be fun for a LUG project!
regards,
Ben

From this article looks like 2.6.12 will be a nice upgrade. http://www.linuxworld.com.au/index.php/id;669959914;fp;16;fpid;0
It will include support for trusted computing and SELinux and Xen and Reiser 4. I've been reading about SELinux (security enhanced Linux) and I think it will be a great addition. Xen looks like it's going to work great too. I don't know exactly how it works. If you run Xen in a window or a different shell or what. I know you can be running multiple OS's which will be nice. I don't know much about the Reiser 4 system I sure it will only add to the popularity of GNU/Linux. I can't wait till the major distro's upgrade to the new kernel 2.6.12.
