Please quit spouting this nonsense.  He's asking for facts not uninformed
opinions.  In both type 1 and 2 hypervisiors the guests run in a protected
CPU state(s) and in that regard they are functionally equivalent.  If you're
actually interested in learning more, Randal L. Schwartz posted a great
interview with some Virtualbox devs awhile ago that gave detailed technical
info.

This is best recent benchmark I see, but it's still old.

IMO it's particularly unfair to Xen with such an old version.  Xen 4 is much
better.

So in regards to the OP's questions, Vbox is your only viable alternative is
you want to run FreeBSD as the host.

HRL is supposed to be coming down the pipe, but I think we're at least a
year away.
