Prior to this change, trunk bridges are created by os-vif but deleted by Neutron when the last vif is removed from it. This creates race conditions in some use cases, like DPDK with vhostuserclient mode, when VMs are rebooted. To avoid these races, Neutron will not delete trunk bridges anymore. Their creation and deletion will be os-vif's responsiblity. Since [1], Nova uses the os-vif version that contains this functionality. This patch also changes the trunk status change event. During a live migration, when the trunk parent port has been bound to the destination host (that means there is only one port binding associated) and the status has changed to ACTIVE, the method triggers the subport binding to the new host too. This is because there could be a race condition between the subport binding, triggered by the OVS agent, and the parent port binding, triggered by Nova. If when the OVS agent tries to bind the subports, the parent port is still bound to the source host, the subport binding remains in the source host too, instead of changing to the destination. This patch also reverts [2] and [3]. As commented in the previous paragraph, this patch fixes the issue reported in LP#1997025. The trunk port live migration with ML2/OVS must be fixed with this patch.
