BHyve vm console 'all ports busy'

[byrnejb]

I connected to a vm guest from the system console using

vm console guest

. When I tried to exit the console using

<shift>~<shift><ctrl>D

I was unable to do so and could not regain control of the system console from the guest.. I conected to the bhyve host via ssh and attempted to connect to the guest console from there. When I tried this I encountered an error, "all ports busy" . I tried shutting the guest down using but that did not work. I then used

bhyvectl --vm=guest --destroy

to stop it and then used

vm start guest

to restart it. I still get the 'all ports busy' and now I cannot connect to the guest via ssh either because it is stuck in the bootloader stage.

How do I clear the console and get this system back on line?

killall cu
(From sysutils/iohyve script).

I don't use any assist programs for bhyve except tmux. All handmade. Good learning experience.

Here is my /etc/rc.shutdown.local

#!/bin/sh
pkill bhyve; ##<< This sends a signal to the VM to shutdown<<##;
sleep 10; ##<< This gives the VM 10 seconds to shutdown cleanly. Adjust to suit your VM's<<##;
bhyvectl --destroy --vm=freebsd1;##<< This section destroys the VM containers.<<;
bhyvectl --destroy --vm=freebsd2
bhyvectl --destroy --vm=freebsd3
bhyvectl --destroy --vm=freebsd4
#bhyvectl --destroy --vm=freebsd5
tmux kill-server;##<< This destroys the tmux console server<<##;

The issue was ultimately resolved by restarting the bhyve host.
