Let's say I wanted to have many different OS's installed on a machine(OSX,BSD,Linux,Winblows because why not) rather than figure out a way to boot all of them and get them to work in harmony(which I believe would be rather difficult with potential for fuck-ups later) is there an 'OS' for virtuallizing all of these? with hardware acceleration support?(say if I wanted to play some games on windows)

I do enjoy my bspwm setup and virtualbox messing around, but sometimes I want a little more to dick around with.

Thanks,
