This bug is awaiting verification that the linux/5.15.0-43.46 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Connectivity testing between DB containers located on different nodes will show there is unexplained sporadic packet loss preventing proper communication between the DB related apps. This will happen when the following conditions are met: 1. Control plane (oam, internal spaces) is configured as vlan interfaces on the same OVS bridge used for data plane (over high speed NIC with HW Offload capabilities). 2. OVS was set with HW offload=true (will happen by OVN chrams after Vault initialization) 3. NIC was not yet set to "switchdev" mode (netplan file will be created by OVN chrams after Vault initialization, however will take affect only after node is rebooted) The root cause is the following missing kernel patch: https://patchwork.kernel.org/project/netdevbpf/patch/20220531205447.99236-3-sa...@kernel.org/ To reproduce: Deploy charmed openstack with HW offload while using control plane on the high speed NIC OVS bridge. Before initializing Vault login to one of the innoDB instances and ping the other 2 instances - all ok. Manually enable OVS HW Offload, ping will become inconsistent. Workaround: After the deployment bring-up phase, BEFORE enabling Vault, login to the nodes and manually create 150-charm-ovn.yaml (example below). Then reboot one node after another. When nodes recover proceed with Vault initialization to complete the deployment. #root@node3:/home/ubuntu# cat /etc/netplan/150-charm-ovn.yaml ############################################################################### # [ WARNING ] # Configuration file maintained by Juju.
