>Description:
NetBSD/i386 8.0 fails to boot in bhyve under both FreeBSD 11.2 an FreeBSD 12.0 

When attempting to boot in bhyve (with debugging on in bhyve) the following message appears in the bhyve.log and bhyve terminates.

vm exit[0]
        reason          VMX
        rip             0x00000000c091f843
        inst_length     7
        status          0
        exit_reason     2
        qualification   0x0000000000000000
        inst_type               0
        inst_error              0

Looking into the VMX reference manual an exit_reason 2 implies a Triple fault occurred in the logical processor.

Attempting to boot NetBSD/amd64 8.0 under the exact same conditions work without issues.
>How-To-Repeat:
Configure a bhyve instance and try booting the NetBSD/i386 8.0 ISO.
>Fix:
I do not know how to debug / fix this problem. 

But I would be more than happy to help investigate this further if someone can help / guide / handhold me into figuring out where exactly this problem lies.

 This is a bhyve issue, not a NetBSD one.

 If you can provide me with a bit more of information as to why it is a
 bhyve issue and not NetBSD I could raise a bug with FreeBSD and follow
 it up there.

 All I have now to go on is the output of the bhyve.log that I posted
 in the original ticket.

 Well, it boots on real hardware, in VirtualBox, QEMU, XEN, ...

 Unless you see some part of the kernel output already and it fails in
 some virtualization specific device drivers it is hard to imagine
 this could not be a fault of the virtualization environment.

 Alright, it makes sense from a birds eye view.

 Let me raise a ticket with FreeBSD and see what the response is.

 Thank you for the insight.
