Open Stack

Hi,

we encountered some problem on our setup with openvswitch with multiple 
nodes.
When openstack is running ok and we restart openvswitch on 2 or more 
compute nodes, flow tables on br-int will be cleared and 
quantum-plugin-openvswitch-agent will not re-configure it until it will 
be restarted too.
Ports are still attached to br-int but without flows.
So after flows are cleared there occur loop on network.

We want to fix it by modifing openvswitch init script to dump/load flows 
when stop/start/restart, it dont do it automatically. Or another 
alterantive is forcibly remove br-int when stopping openvwswitch.

And of course automatically restart quantum-plugin-openvswitch-agent 
after openvswitch restart.

Anyone encounter same problem and/or have some better solution ?

Thanks
