Hello,
I switched my notebook from a ThinkPad X230 to ThinkPad T480
(each running 12.1). I noticed that one of my OpenBSD (6.3)
bhyve VMs is not booting anymore. It stops with a debugger
prompt:

Does anyone know why / how to boot the VM?
This VM runs fine on the X230 model but not on the T480.
Other guests (FreeBSD, Ubuntu) run fine on the T480 model as
well.
Thanks!
