OpenBSD fails to boot on bhyve on AMD hardware

[akole]

When booting bhyve branded VM with OpenBSD 6.6 install iso the process fails with:

{"log":"vm exit[0]\n\treason\t\tSVM\n\trip\t\t0x00000000fffee1ec\n\tinst_length\t0\n\texitcode\t","stream":"stderr","time":"2020-04-23T17:27:36.533033000Z"}

SmartOS platform is joyent_20200408T231825Z
Server is a Proliant DL385 G6 with dual AMD Opterons

Have you tried adding vmadm update UUID bhyve_extra_opts="-w" it's needed on intel too to not make OpenBSD trip bhyve by accessing unsupported MSRs

Yes, I set these in the spec json and both seem to be there when checking vmadm info:
"bootrom": "uefi",
"bhyve_extra_opts": "-w"

Ack, should work then... so it's probably a SVM vs VMX thing.

Anything I can do to help debug this issue?

FreeBSD host with NetBSD VM also seemed to have similar issues few years back if it's any help:

@akole this should be fixed in the latest platform image, got to a normal multi-user boot with multiple vcpus configured
