You could take a different approach, and not use virtual machines at all ! Why not install the linux distro of your choice on some decent sized server or group of servers. Something with a decent cpu power and ram. Then, on your developer machines install an X windows system. Something like the commercial exceed package or the free cygwin/X package. This will allow your developers to start full remote X sessions on your linux servers and use them directly for the compilation tests etc. > > Bo Berglund
