Hi,

booting a custom FreeBSD main kernel:

...
WARNING: WITNESS option enabled, expect reduced performance.
PPIM 0: PA=0xb8000, VA=0xffffffff82c10000, size=0x8000, mode=0
pmap: large map 8 PML4 slots (4096 GB)

and I get a

bhyve exited with code 0

Sometimes I wish we'd be more verbose...  I don't see anything in dmesg either.

How do you debug what's going on?
