[Bug 1601820] Re: ovs-vsctl is hanging

[ChristianEhrhardt]

Hi,
"ovs-vsctl show" can display only the DB config entries - so that show works is no guarantee that it is actually running. In case it is not running the described behavior occurs.

If you just want to go on configuring (without actually starting the
vswitch) you can add --no-wait to the ovs-vsctl commands
(http://openvswitch.org/support/dist-docs/ovs-vsctl.8.txt).

But eventually you want to find out why it isn't running to begin with.
I recommend checking the logs, I just added a section on troubleshooting but it is not yet in the published serverguide (https://help.ubuntu.com/16.04/serverguide/DPDK.html).
Until it is published I recommend this for troubleshooting: http://askubuntu.com/questions/786510/using-openvswitch-with-dpdk-in-ubuntu-16-04/789203#789203

Title:
  ovs-vsctl is hanging

Status in openvswitch package in Ubuntu:
  Incomplete

Bug description:
  Hi,

  I am following the document to install OVS DPDK in Ubuntu 16.04

  https://insights.ubuntu.com/2016/05/05/the-new-simplicity-to-consume-
  dpdk/

  I installed.

  When I run 
  $sudo ovs-vsctl add-br br1 -- set bridge br1 datapath_type=netdev  , 

  it hangs, and it does not show any result.
  But when I opened another terminal, i run sudo ovs-vsctl shop.

  It shows bridge.
  When I do delete command, it hangs again.

  Do you know why?

  Thanks
