The only way I'm aware of to do this on FreeBSD is to use qemu with the 
lkvm module from - I haven't 
had any success with it (qemu crashed shortly after starting) but it 
might just have not liked my amd64 installation.   The other thing that 
has worked for me in the past is kqemu in ports - it enables qemu to run 
a /lot/ faster by running code natively instead of having to interpret 
each instruction.
