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. http://www.ilsistemista.net/index.php/virtualization/1-virtual-machines-performance-comparison.html 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. http://wiki.freebsd.org/Hierarchical_Resource_Limits -- Adam Vande More
