Public bug reported: Running the Bionic/Ussuri OpenStack cloud with Neutron/ML-2 OVS virtual networking and hardware offload enabled on the NIC level [1]. The cloud has 6 nodes with 2 host aggregates, 3 nodes each. The cloud has 2 vlan physnets, each spanning the corresponding host aggregate; and 1 flat physnet spanning all 6 nodes.
I'm deploying charmed Kubernetes to one of the host aggregate using VLAN provider network. Despite it was working initially, after some time it is not possible schedule a VM to this host aggregate with "Port binding failed" error due to a timeout. The existing VMs typically continue to work and be reachable over the network as expected. The other symptom is that OVS commands like 'ovs-appctl' hang. The workaround to this problem is to restart OVS, but this helps only temporarily. Tried with both port security turned on and off on the network level.
