Running Trixbox in Xen

A week ago I was searching if we can run multiple Trixboxes on one physical server.
Trixbox is all in one solution which can be easily deployed and sold as virtual PBX for small company. I have found nice howto at Engineer Tim’s blog. There is also update for new Trixbox 2.8, which I have used. Using this howto I have now clean Trixbox installation on LVM as logical volume. New PBX can be deployed in few minutes and we don’t need physical server for each customer.
