This looks like illumos#12998 which is fixed in 20200813T030805Z or newer. I'd try a platform image with that fix and see if that solves the issue. |
There are two failures at play here, AFAICT. The first is the wrmsr failure, which indeed should be helped by #12998. The second is the failure decoding the |
just got around to testing this with the platform image from a week or two ago, fix is confirmed. thank you so much! |
side note: does bhyve expose any kind of keyboard? it has a USB 3.x tablet as a pointing device but i can't type anything into a on windows at least i can summon the on-screen keyboard until i configure RDP enabled |

The instruction stream is
