Sort of, yes.  I've actually just started using it myself, so I don't know that much about it.  Thus far, it does not seem all that promising, esp. since getting any sort of decent performance out of a Linux VM requires installing new kernel modules to the guest.  I'll continue working with it, though, and I'll try to let this list know what I find.

Can this be a GPL equivalent of VMware?
