lxc version: 5.0.1
kernel version is 6.0.7
gentoo
i execute
$ lxc start archcon
without any error, and $? is 0, but the container is not really started. it is still stopped.
when i execute lxc info archcon, it prints:
Name: archcon

Does it work without being privileged or on a different kernel?
What does lxc info <instance> --show-log show?
lxc info archcon --show-log (this is a archlinux container image that created some days ago)

And I also created a ubuntu container whose name is ubuntucon:

Can you run lxc monitor --type=logging --pretty in one terminal and then try starting a container and collecting the output here. Thanks

Is your Gentoo on openrc, and the container is systemd (as it is arch it most likely is?)
If yes, make sure your kernel has openrc and systemd support,
# zgrep -i gentoo_linux_init /proc/config.gz
CONFIG_GENTOO_LINUX_INIT_SCRIPT=y
CONFIG_GENTOO_LINUX_INIT_SYSTEMD=y
and do this in your host:
root #install -d /sys/fs/cgroup/systemd
root #chown root:lxd /sys/fs/cgroup/systemd
root #mount -t cgroup -o none,name=systemd systemd /sys/fs/cgroup/systemd
And try again.

Thank you very much. Following your guide, it works well, although CONFIG_GENTOO_LINUX_INIT_SCRIPT and CONFIG_GENTOO_LINUX_INIT_SYSTEMD can’t be even found in /proc/config.gz
