Public bug reported: This is a race condition.
Given a cloud with 0 compute nodes available, on a compute node: * Start up neutron-openvswitch-agent * Start up nova-compute * nova boot an instance Scenario 1: * neutron-openvswitch-agent registers with Neutron before nova tries to boot instance * port is bound to agent * instance boots with correct networking Scenario 2: * nova schedules instance to host before neutron-openvswitch-agent is registered with Neutron * nova instance fails with vif_type=binding_failed * instance is in ERROR state I would expect that Nova would not try to schedule instances on compute hosts that are not ready.
