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:

  driver: lxc

  kernel: Linux
  kernel_architecture: x86_64

  server_pid: 4426
  server_version: "2.16"
  storage: zfs
  storage_version: 0.6.5.6-0ubuntu16

** Description changed:

- 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:

-   driver: lxc
