Pavel, sorry - ignore my previous email and don't run quantum-ovs-cleanup. Steps should be:
- stop quantum-ovs-plugin-agent - stop openvswitch services - start openvswitch services - start quantum-ovs-plugin-agent Re, Darragh. >________________________________ > From: Darragh O'Reilly <[email protected]> >To: "[email protected]" <[email protected]> >Sent: Thursday, 26 September 2013, 13:37 >Subject: Re: [Openstack] loop on network with openvswitch + vlans > > > >Pavel, > > > > why are you restarting Open vSwitch?
