Re: Failed to emulate instruction sequence [ 41f646040874064c017d88eb144c89 ] at 0xbea5fcf9

ok I've used this :

.op_flags = VIE_OP_F_IMM8

After the compilation is finished,I copied the compiled vmm.ko module
from /usr/obj/usr/src/amd64.amd64/sys/modules/vmm/vmm.ko
to /boot/kernel and to /boot/modules.

Regarding the bhyve executable,I'm using two custom versions of it,called
bhyve-lin and bhyve-win. When I upgrade the system,they cannot change. What
can change is bhyve,but I don't use it. In addition,to be sure,I copied
bhyve-lin and bhyve-win from the system where I don't have the error. With
this being said,the recompilation of vmm.ko didn't solve my issue.
