Currently I installed VMWare on a dual opteron system (with 4GB memory). At this moment I have installed the next virtual machines:
- Debian 4.0 r1
- RedHat Enterprise Linux 5
- Solaris 10
Everything works fine and I use it to play with the different systems in preparation of the LPIC1 stuff…
The next step will be installing different ‘virtual nodes’ to play around with it as if it is a cluster. 
And play with parallel programming stuff using ‘Message Passing Interface’… one thing I wish to do for a long time 
It is really cool stuff to play with!
