--- Comment #8 from Jordan Hubbard <jkh at ixsystems.com> ---
I think this ticket may have been closed a little too hastily.  The FreeBSD bug
is right there in the sysctl output:

hw.vmm.vmx.cap.unrestricted_guest: 0

However,
http://ark.intel.com/products/41316/Intel-Core-i7-860-Processor-8M-Cache-2_80-GHz
on this product claims otherwise.  Reference FreeNAS ticket:
https://bugs.freenas.org/issues/22362

FreeNAS relies completely on the sysctl output for hw.vmm.vmx / hw.vmm.svm
(AMD) to tell it whether chipset supports VT-x, EPT and AMD-V CPU features
respectively.
