Bug Description

Command 'service openvswitch-switch status' gives wrong status report, when process is already running and when it is not running:

Then if process will be killed or stopped (for example, kill -9):

# kill -9 17623
# kill -9 19084
#
# ps auxf | grep openvswitch
root 19129 0.0 0.0 12948 1004 pts/1 S+ 13:19 0:00 \_ grep --color=auto openvswitch

We still have same status report:

This is due to the slight nasty way that ovs was originally integrated with systemd; I think there is a nicer approach using systemd to manage the individual daemons so we should look to see if we can switch to that model.

  * Drop obsolete upstart configuration file.
  * Bump nofiles to 1048576 for ovs daemons (LP: #1737866).
  * d/control: Bump minimum debhelper version to 10, drop BD on

    Cherry pick in-flight fixes for workaround to correctly set MTU
    of GRE devices via netlink (LP: #1742505).
