Sahana has been donated a dedicated server by [http://zen.co.uk Zen Internet].

This runs Xen to allow us to have a few different machines protected from each other.

Dom0 is run on Ubuntu 804:
 * http://www.howtoforge.com/ubuntu-8.04-server-install-xen-from-ubuntu-repositories
 * http://wiki.xensource.com/xenwiki/XenNetworking

We then have !DomUs running the same OS for:
 * Trac
 * Demo
 * Testing
 * Hackfests
 * IRC bot
  * Phenny (Trac updates like #openlayers)
  * TalkSahana Twitter channel updates: http://code.google.com/p/python-twitter-bot/

The Hackfest machine can be turned off between hacks to free up resources for the other systems.

The hackfest machine includes a Bzr repository & an Apache/WSGI instance with Admin accessible remotely.
There is a CGI available to restart Apache when-needed.

The Testing machine could include a desktop accessible via VNC:

Both VM technologies can be managed using [http://openqrm.com OpenQRM] in a [http://sourceforge.net/mailarchive/forum.php?thread_name=6b7f6eb0812151112x797ee320l5e4b2ceebadfbe7e%40mail.gmail.com&forum_name=openqrm-user DomU].

==== VMWare ====
Would be good to also add a Windows Test environment in [http://www.howtoforge.com/how-to-install-vmware-server-2-on-ubuntu-8.10 VMWare Server], but VMWare can't run with a Xen kernel :/[[BR]]
(This CPU doesn't include [http://www.virtuatopia.com/index.php/Virtualizing_Windows_Server_2008_with_Xen vmx support] :/)
