Hi Pippin, In general case, you can run an agent on the compute node. The agent can handle transactions sent by the controller node, when VMs destroyed/stopped/started. Then, the agent will set/unset the tag of VMs according to information which be sent by the controller. The VLAN of the

Hi Pippin, The VM’s tap devices will been destroyed when the physical host is powered off. So, the OVS can’t find the tap device of VMs when the OVS service restarted. When you start the VM, the tap inserted in OVS bridge is a new tap and the tag is reseted as default. The command

First off I apologize for submitting a "bug" on such an old version but what I am trying to find is the first "stable" OVS version where this bug is fixed and move it it for now. The situation is that the majority of our VM's running under KVM will have changed vlan tags when the physical host i
