Yes, exactly--that's its main benefit I think. For casual testing, for
things like running a client to quickly test ldap, that sort of thing, I
find it quite handy. 

I haven't done any benchmarks in a long time, save for an almost useless
one, compiling FreeBSD make buildworld--VBox was about an hour slower
than VMware-player, and KVM-qemu was faster by about 10 minutes--that
is, faster than VMware.  

So, my REALLY subjective impression is that KVM-qemu (on a supported
CPU) is somewhat faster than VMWare-player--the new one--which is faster
than VirtualBox.  VMware-player and VirtualBox are probably about equal
in ease of use, VBox is smaller, possibly a bit faster to set up. 

Going to re-title this one post as it had nothing to do with the OP's
question.

idea how lonely it is, how dangerous? I would love to be upstairs
watching TV or gossiping about boys or... God, even studying! But
I have to save the world. Again.
