That is a really good use of virtual x86. Now I'm looking at my developer
setup and thinking that I have too many machines, too many boot options.
Instead I should have one really high powered laptop that runs Linux and
MS Windows side by side instead of dual boot. And a third VM running
as a Hackintosh.
