A server for nightly builds. (was: Nightly builds)

[Casper van Donderen]

SuSE Enterprise. My high school runs two win server 2k8 instances on that since they need Windows. That is a quad-core with 8G RAM though...

yes, in the opposite some more efforts required on the host, see network 
issue below

seems no problem on a server  with good performance - from 
http://en.wikipedia.org/wiki/VirtualBox "VirtualBox achieves a 
performance that is comparable to that of VMware"

the drawback is that harddisc of a will probably be huge - i guess about 
25-40 GB for a single vm.

- Does anyone have free windows license  xp, vista, windows 7 ? 64 
releases ? I remember that some mdsn packages contains os licenses.

Some notes:
- On many root server there is - in vmware terms - "no bridged network" 
possible.  According to 
http://kex.cc/2006/09/16/vmware-auf-einem-rootserver-betreiben/ (only 
german)  vm's have to use nat and on the host a private network has to 
be installed

There are also the following questions:
- Which linux os is prefered ?   (I personally only have knowledge with 
opensuse)
- Does anyone have experience installing virtualbox on a root server ?
- Does anyone have enough knowledge to deal with the above mentioned 
network issues ?
