Take a look in /var/log/neutron/openvswitch-agent.log, or similar, on the 
hypervisor.

[openstack-dev] [neutron]Where did the flows go in ovs bridge?

[Zhi Chang]

hi, guys.


I deployed DVR in my local environment by following  this 
document(https://wiki.openstack.org/wiki/Neutron/DVR).  And I have three 
compute nodes which running DVR l3-agent and two network nodes which running 
DVR_SNAT l3-agent.


I created a vm in one of the computes nodes. And flows was generated 
normally. But, all flows are gone when I  restart "neutron-openvswitch-agent"!. 
I wait a few minutes but I can't see any flows were generated. 


Could someone tell me why the flows are gone and they can't generated 
anymore?




Thanks
