bhyve vm console connects but do not get session prompt

[byrnejb]

When I attempt to connect to the serial console of a Rocky Linux 8.8 bhyve guest I do not get a shell prompt:

[root@vhost03 ~ (master)]# vm console vhp3k101rl88
Connected

I can connect via ssh. Does anyone have an idea as to why I do not seem to get a shell via cu?

Most Linux distributions don't enable a serial console by default any more.

Is this a repeat of https://forums.freebsd.org/threads/vm-console-guest-gives-stale-lock-and-will-not-break.89507/

No it is not a repeat although it may be related to the stale lock problem. Note that I get a connection on the serial port. I also get echo-back on character transmission. I just do not get a shell. I have previously connected to the serial console during bootup of this guest and later. This is a new behaviour.

Back to the stale lock problem again.

[root@vhost03 ~ (master)]# vm console vhp3k101rl88
Stale lock on nmdm-vhp3k101rl88.1B PID=79780... overriding.
