Comment 1 for bug 1471022

So, this is possibly a result of neutron-ovs-cleaunp failing to start at the time nova-compute does the wait-for-state (and implicitly tries to start neutron-ovs-cleanup) due to the fact that openvswitch is not ready to start at that very moment. I am going to attempt to resolve this by making the nova-compute wait-for-state logic more accommodating of the fact that neutron-ovs-cleanup may not be ready to start at the time of the check.
