These tests will try to create ip6gre and vti6 virtual interfaces and systemd-networkd is failing to create them starting on kernel 5.15.0-83.92. As far as I can tell, kernel 5.15.0-82.91 is the last revision where it works. So, some change between 5.15.0-82.91 and 5.15.0-83.92 is causing this regression. How to reproduce the issue: # Launch a jammy cloud VM: lxc launch images:ubuntu/jammy/cloud jammy --vm lxc shell jammy # Create a netplan file that creates 2 tunnels: cat > /etc/netplan/10-tun.yaml <<EOF network: renderer: networkd version: 2 tunnels: tun0: mode: ip6gre local: fe80::1 remote: 2001:dead:beef::2 tun1: mode: vti6 local: fe80::2 remote: 2001:dead:beef::3 EOF # Apply the configuration netplan apply # Check with "ip link" that both tun0 and tun1 *were not created* and check networkd for errors: journalctl -u systemd-networkd Sep 28 17:04:40 jammy systemd-networkd[360]: tun0: netdev could not be created: Invalid argument Sep 28 17:04:40 jammy systemd-networkd[360]: tun1: netdev could not be created: Invalid argument # Download, install and boot on kernel 5.15.0-82.91 wget http://ie.archive.ubuntu.com/ubuntu/pool/main/l/linux-signed/linux-image-5.15.0-82-generic_5.15.0-82.91_amd64.deb http://ie.archive.ubuntu.com/ubuntu/pool/main/l/linux/linux-modules-5.15.0-82-generic_5.15.0-82.91_amd64.deb dpkg -i *.deb grub-reboot '1>2' && reboot # Check with "ip link" again that both tun0 and tun1 were created # Reboot again to go back to the most recent kernel and check with "ip link" that both tun0 and tun1 were not created. --- ProblemType: Bug AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Sep 29 12:52 seq crw-rw---- 1 root audio 116, 33 Sep 29 12:52 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.20.11-0ubuntu82.5 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' AudioDevicesInUse: Error: [Errno 2] No such file or directory: 'fuser' CRDA: N/A CasperMD5CheckResult: unknown CloudArchitecture: x86_64 CloudID: lxd CloudName: lxd CloudPlatform: lxd CloudSubPlatform: LXD socket API v. 1.0 (/dev/lxd/sock) DistroRelease: Ubuntu 22.04 IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' Lspci: Error: [Errno 2] No such file or directory: 'lspci' Lspci-vt: Error: [Errno 2] No such file or directory: 'lspci' Lsusb: Error: [Errno 2] No such file or directory: 'lsusb' Lsusb-t: Error: [Errno 2] No such file or directory: 'lsusb' Lsusb-v: Error: [Errno 2] No such file or directory: 'lsusb' MachineType: QEMU Standard PC (Q35 + ICH9, 2009) Package: linux (not installed) PciMultimedia: ProcEnviron: TERM=screen-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: 0 virtio_gpudrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.15.0-84-generic root=/dev/sda2 ro quiet splash console=tty1 console=ttyS0 vt.handoff=7 ProcVersionSignature: Ubuntu 5.15.0-84.93-generic 5.15.116 RelatedPackageVersions: linux-restricted-modules-5.15.0-84-generic N/A linux-backports-modules-5.15.0-84-generic N/A linux-firmware N/A RfKill: Error: [Errno 2] No such file or directory: 'rfkill' Tags: jammy uec-images Uname: Linux 5.15.0-84-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: N/A _MarkForUpload: True dmi.bios.date: 2/2/2022 dmi.bios.release: 0.0 dmi.bios.vendor: EDK II dmi.bios.version: unknown dmi.board.name: LXD dmi.board.vendor: Canonical Ltd. dmi.board.version: pc-q35-8.0 dmi.chassis.type: 1 dmi.chassis.vendor: QEMU dmi.chassis.version: pc-q35-8.0 dmi.modalias: dmi:bvnEDKII:bvrunknown:bd2/2/2022:br0.0:svnQEMU:pnStandardPC(Q35+ICH9,2009):pvrpc-q35-8.0:rvnCanonicalLtd.:rnLXD:rvrpc-q35-8.0:cvnQEMU:ct1:cvrpc-q35-8.0:sku: dmi.product.name: Standard PC (Q35 + ICH9, 2009) dmi.product.version: pc-q35-8.0 dmi.sys.vendor: QEMU To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2037667/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
