Hi,
we use Ubuntu server pretty extensively for virtualisation and have been 
disappointed with the performance and stability of Xen in general. This 
has nothing to do with Ubuntu because we have tried Xen from source, 
packaged our own latest versions with new kernels etc.
So we are now migrating everything to OpenVZ. We have backported vzctl 
and deps to dapper and have a decent 2.6.18openvz kernel. Very happy 
with openVZ - it understands whats its trying to do alot more than Xen, 
is rock-solid, and does cool stuff like live-migrations without shared 
storage! Its linux only of course, but thats fine if all you care about 
it Linux...

OpenVZ is the opensource version of virtuozzo, from Swsoft. The 
development team is really active and getting 2.6.22 support is steaming 
ahead.
