Greetings,
I have a similar problem with Xenial, though I have not found any
solution (I am not familiar with systemd and the solution provided for
CentOS does not apply to Xenial).
I created a few days ago a new container on an updated Ubuntu Trusty
Thar 14.04 LTS host using the following command:
lxc launch images:ubuntu/xenial/amd64 server1
Now, it hangs when I run:
lxc stop server1
This problem was reported at https://github.com/lxc/lxd/issues/1570 [3]
What puzzles me, is that stopping a container is such a basic feature
that I am surprise to find that it is not being addressed. Both Trusty
and Xenial are now out and production ready, yet one cannot stop a
Xenial container. Are we the only one that have this problem? Should I
open a new bug report or can someone open this one again since it is not
fixed?
Best regards,
Hans Deragon

Hi all,
I was trying lxc on Ubuntu 16.04 LTS and found out that
lxc stop does not stop a CentOS 7 container.
I ran the following commands.
lxc image copy images:/centos/7/amd64 local: --alias=cent7
lxc launch cent7 cent01
lxc stop cent01
^ This does not stop the cent01 container even after one minute,
so I pressed Control-C to kill this command.
I found a workaround at

Here is a command to fix.
lxc exec cent01 -- sh -c 'ln -s /usr/lib/systemd/system/halt.target
/etc/systemd/system/sigpwr.target && systemctl daemon-reload'
After this fix, the container is stopped immediately with
lxc stop cent01
I would like to this fix to be included in the original image.
How can I contact the maintainers of container images?
Here are versions of lxc and CentOS 7 image.
$ lxc version
2.0.0
$ lxc image list cent
