Troubleshooting
LXC containers does not start networking
I have a Fedora based LXC container which takes a long time to start up. After the tty does start, the only network adapter isn't up. systemd-networkd is also in a a failed state with a bad exit code and status 226/namespace.
This was resolved by enabling nesting on this container with the following commands:
# pct set $CTID -features nesting=1
# pct reboot $CTID
