I'm on current xenial, lxd version is 0.23, which you confirmed had this
issue:
$ lxc --version
0.23
I created a wily and xenial container:
$ lxc launch images:ubuntu/wily/amd64 w1
$ lxc launch images:ubuntu/xenial/amd64 x1
"lxc stop" works for both w1 and x1. When I follow (-f) the journal in
a container with
$ lxc exec x1 -- journalctl -f
before "stop", it starts with
Dec 01 05:47:43 w1 systemd[1]: Received SIGPWR.
Dec 01 05:47:43 w1 systemd[1]: Failed to reset devices.list on
/lxc/w1/system.slice/sigpwr-container-shutdown.service: Permission denied
Dec 01 05:47:43 w1 systemd[1]: Starting Shut down containers on SIGPWR...
and then a lot of shutdown messages. I suppose your journal output in
comment #6 was from *after* you did "lxc stop"? If not, please re-send
it.
Let's check for you that everything is in place. Can you please
copy&paste the output of
$ lxc exec test -- ls -l /lib/systemd/system/sigpwr.target.wants/sigpwr-
container-shutdown.service /lib/systemd/system/sigpwr-container-
shutdown.service
$ lxc exec test -- systemd-detect-virt
and then *after* running "lxc stop", the output of
$ lxc exec test -- systemctl status -l sigpwr-container-shutdown.service
Thanks!

This is a follow-up on this issue here:
https://github.com/lxc/lxd/issues/1336 I cannot stop a LXD container
gently and as it seems the issue lies within ubuntu/systemd which does
not handle SIGPWR correctly.
