[Bug 1601820] Re: ovs-vsctl is hanging

[Alan Deikman]

I have worked past this issue for now.  I think the most common reason
that ovs-vsctl hangs is because ovs-vswitchd is not actually running.
The systemd mechanism (service openvswitch-swith start|stop|status) can
get confused by openvswitch because it is likely that ovsdb-server is
running even if ovs-vswitchd didn't manage to start.

Look in the error longs in /var/log, particularly /var/log/apport.log.
In my case it turned out to be a memory allocation problem with huge
pages.  Once that was fixed I was able to proceed.

  ovs-vsctl is hanging

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
