Hi , I have a 2 node setup of openstack (devstack). One is controller+compute with ODL running on it and another is compute node, with ODL integrated. After I restart my ovs switch all the default flows gets created,my vm gets the ip and things are fine.But after some time the flows on OVS (table 30 to table=100) gets deleted. So next time when I try to launch any instance new ovs-port is created but the action for it is "goto table=20" and onwards, which doesn't exist. Hence my VM don't get the IP address from DHCP.

Any help what is going wrong here.

Excerpt from ovs-vswitchd.log after I restart the OVS
