I use Xen + OpenVZ on a build machine.

I need to build binaries of an Open Source software package I maintain.

So I have a Xen PV OpenVZ DomU that hosts a container for each Linux 
Distro and Version I need to build.

For those non-Linux OSes like Windows, FreeBSD and Solaris I use either 
Fully or Para Virtual Xen DomUs to do the build.

Then when I'm doing a release I run a script on my development machine.

The script starts the various virtual environments, copies over the 
source tar, builds it, copies back the binaries and stops the virtual 
environment.

In about a half hour I end up with about 40 OS and Version specific 
RPMs, DEBS, etc.
