Has anyone used Virtualbox?

I think Sun owns it now?

I read it in my LXE Format magazine.

It sounded like it was basically like XEN, but with snapshot abilities
(they said it could run paravirtualized stuff).

To me, the snapshot is what makes VMWARE so much better than XEN (yeah,
you can do a sort-of-snapshot with LVM, but that's not quite the same).
