Title: LXD 4.2 broken on linux-kvm due to missing VLAN filtering Status in linux-kvm package in Ubuntu: Triaged Bug description: [Description] Some VLAN options (BRIDGE_VLAN_FILTERING, and its dependencies VLAN_8021Q*) were in a different state in Focal/kvm compared to Focal/generic: LXD now depends on BRIDGE_VLAN_FILTERING and due to this discrepancy it fails to work on the Focal/kvm kernel: fix it by aligning the config with Focal/generic [Fix] Apply the attached config patch [Regression potential] Low, just some config changes already present in generic. --- This is another case of linux-kvm having unexplained differences compared to linux-generic in areas that aren't related to hardware drivers (see other bug we filed for missing nft). This time, CPC is reporting that LXD no longer works on linux-kvm as we now set vlan filtering on our bridges to prevent containers from escaping firewalling through custom vlan tags. This relies on CONFIG_BRIDGE_VLAN_FILTERING which is a built-in on the generic kernel but is apparently missing on linux-kvm (I don't have any system running that kernel to confirm its config, but the behavior certainly matches that). We need this fixed in focal and groovy.
