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.
