The last two lines are key. Add these flags: -F -o logfile. The default loglevel is ERROR. If you want more detail include -l LEVEL.

This is what I get:

I guess the first two lines are the key to the problem. My default config file is:
$ cat ~/.config/lxc/default.conf lxc.net.0.type = veth lxc.net.0.link = lxcbr0 lxc.net.0.flags = up lxc.net.0.hwaddr = 00:16:3e:xx:xx:xx lxc.idmap = u 0 100000 65536 lxc.idmap = g 0 100000 65536
The 'test' container is a Fedora 39 instance.
