I'm looking for a Linux VPS system for my hosting business. I know about the options, Xen, V-server, Virtuozzo, UML, but frankly I don't have time to roll my own setup. I need the following:

- turnkey, easy to setup.
- supported. can buy support and get pro help quickly in an emergency
- reasonably-priced. not el cheapo or super-expensive.

I am an advanced BSD admin but don't have much Linux experience.

If someone is selling a Xen-based system I would really like to know about it.

Any suggestions?
