bhyve -G <port>

Any hints on how to use bhyve's -G <port> option to debug a VM
kernel? I can connect to it from gdb with "target remote :<port>"
& bhyve stops the VM initially but beyond that I am not sure. 
Ideally this should work just like an in-circuit-emulator, not
requiring anything special in the VM or kernel itself.

Thanks!
