I am facing a strange problem, where a perfectly running VM becomes unreachable all of a sudden and I have to restart openvswitch agent on the compute to fix it.

This happens in both grizzly and havana with openvswitch networking.

Has anybody faced a similar problem, any pointers will be helpful.

This can happen when a Flow gets deleted from OVS flow table. Please check this by using OVS-ofctl command.

Else, please post the log files.

Thanks for replying Shankar,

I did checked the dump flows and I see a normal flow , so the flows look proper. Also I do not see any errors in logs.

Please let me know which log files you want, I will post them.

Nope, the setup has 2 controllers running nova,glance and quantum/neutron server, 2 network nodes running the neutron agents(dhcp,l3,metadata,ovs) and computes running nova-compute and ovs-agent. VMs are running in compute node.
