I've seen this problem too even when lxc-stop is used and the container
is a Fedora container (mostly F12's). If I shut down the container and
stop it with lxc-stop then restart the container, I get that "failed to
create pty #0) when sshing into the container. I have to restart the
host system once that's happened.

I'm going to have to see if there's something similar in the Fedora
shutdown scripts.
Interesting. I hadn't tried using "lxc-stop" without shutting down the
contained OS, so I hadn't narrowed it down that far. Interesting.
