Same problem using FreeBSD current UEFI guests with bhyve, so it should
happen in any kind of hypervisor.
It is an old regression (in the sense of -current, so older than 6 months).
My idea was to generate very light UEFI VM images (because the snapshot VM
images are BIOS based) and scripting a bisector tool, but I never took the
time to do it.
