Look here for some more info:

In my personal experience it works ok, if you have plenty of memory 
(unlike a Virtual box VM under windows it will fail to start if you 
don't have as much free ram on the host as you have allocated to the 
VM), and are not expecting stellar graphics in the VMs.  Make sure to 
tune your zfs arc max value down so that you keep the memory available 
for the VMs
