[Fedora-xen] Virtual Machine Manager

[gvm999]

Hi all,

This is probably a stupid question, but I can't figure it out...

I want to try Virtual Machine Manager.
When I create a new machine, there is asked for a "Install Media url".

I want to install FreeBSD as a virtual machine, however, what url should I
specify then?
Or is this only for redhat systems? (fedora/centos?)

Greetings!
