We have talked before a while back about virtual machines.

In the past I've used VMware and Microsoft Virtual PC for virtualization so I can run different OSs within Windows. And also PearPC to run Mac OS X. And most of us will have tried DOSBox at some point to try and run older games.

On this months PCPro magazine they have included a copy of Virtualbox which is another similar product, and on looking at its specification it looks like it could be more advanced that Virtual PC, with more control over the hardware emulated on the virtual machine. Has anyone used Virtualbox?

And have you tried any other virtulization software? Which do you think is currently the best?

I found this comparison of available virtual machine software here.
