This works under Ubuntu 10.10. I tried under 10.04 LTS but the Ubuntu templates are not there. Investigating.

[ Leaving this link here for reference in case I need to do apt-get upgrade. @ohloh recommends it
http://sourceforge.net/mailarchive/message.php?msg_id=26885493 ]

To make things easy have libvirt installed ie.

sudo apt-get install libvirt-bin

Otherwise you will need to set up bridges, iptables, dnsmasq.

(16:11:24) jmlowe: just one
(16:11:27) bernardl: ok
(16:11:41) bernardl: how easy is it to setup monetdb? is it readily packaged up in Linux?
