Hi Cory,

 bhyve expects that the CPU supports INS/OUTS exits. This is signalled
in bit 54 of the VMX_BASIC MSR. I'll have a talk with Neel about the
implications of ignoring this bit.

Hmm.  Does Linux KVM ignore it?

 It must do (as did bhyve for a long time).

(does -host not emulate all MSRs?)

Probably just not that bit. You might want to try the this patch which comments out that test, and see if it gets you any further.
