Public bug reported:
If you have ubuntu 16.04 containers running snmpd and you stop the snmpd
on the LXD host system, it will also shut down all the snmpd instances
on the containers (but will not restart them if you restart them on the
LXD host) .. in fact, you even need to go back into the container, stop
the snmpd before you can start it again.
See log below, viepovzat17 is the LXD host, viezmaaat10 is the ubuntu
container:
