Does bhyve work on AMD CPUs under 10-STABLE?  I rebuilt my system=20
yesterday (to r269010) but the bhyve module does not appear to load=20
properly.  I get this on the console when I kldload vmm:

=3D=3D=3D=3D=3D
amdv_init: not implemented
amdv_cleanup: not implemented
module_register_init: MOD_LOAD (vmm, 0xffffffff81c1a590, 0) error 6
=3D=3D=3D=3D=3D

The system has a 6-core AMD FX-6300 CPU:

It has the POPCNT feature, which is the one the bhyve documentation=20
says to look for.

Does bhyve only work on Intel CPUs for now?  Does anyone have it=20
working on an AMD FX-6300-based 10-STABLE system?

Cheers,

Paul.=
