And POPCNT is not all you need on AMD, there are AMD processors with POPCNT that do not have RIP, and RIP is needed for bhyve, the wiki should be updated to reflect that. > > its possible that your E5 is old enough that it lacks the VT-x support > that bhyve needs. I do not believe there are any XEON e5 class CPUs that lack VT-x, as the E5 family's first versions are Sandy Bridge-EN/EP core based chips. -- Rod Grimes rgrimes@freebsd.org
