What's the best way for me to virtualize my computer? I'm not sure which one to use, so I'll have a look at vmx, xen and vmware. Free is kind of important as in speech not beer though.
I apologize for not taking more care with the reply. I do believe, however, that you can be interested in freedom without paying for system administration services.
I would like to say that VMware Server is free (as in beer) and will run Windows VMs just fine.
For what it's worth, I've also used Xen before, and it's perfectly good too.
