I don't know of anybody using it, but for a pure Xen environment how
about using rPath+Xen?

Build a minimal rPath host system with Xen support. The only downside
is you will need to find a Xen management interface for it. Would be
nice if a good web-based Xen management tool existed.

rPath should have the long-term support you are looking for and allows
you to roll your own services to build a custom appliance.
