Public bug reported: This is a potential regression for ARM64 qemu-kvm package (1:2.8+dfsg- 3ubuntu2.8).
With qemu-kvm updated from 1:2.8+dfsg-3ubuntu2.7, the kvm-unit-test in our test suite will fail with: Unexpected error in kvm_device_access() at /build/qemu-2b6oyQ/qemu-2.8+dfsg/kvm-all.c:2151: qemu-system-aarch64: KVM_GET_DEVICE_ATTR failed: Group 6 attr 0x000000000000c664: No such device or address QEMU Aborted Steps: 1. Deploy a ARM64 zesty system 2. git clone https://git.kernel.org/pub/scm/virt/kvm/kvm-unit-tests.git 3. cd kvm-unit-tests 4. ./configure; make 5. sudo ./run_tests -v 6. Enable proposed and upgrade the qemu-kvm package, repeat step 5 $ dpkg -l | grep qemu ii ipxe-qemu 1.0.0+git-20150424.a25a16d-1ubuntu2 all PXE boot firmware - ROM images for qemu ii qemu-block-extra:arm64 1:2.8+dfsg-3ubuntu2.7 arm64 extra block backend modules for qemu-system and qemu-utils ii qemu-kvm 1:2.8+dfsg-3ubuntu2.8 arm64 QEMU Full virtualization ii qemu-system-arm 1:2.8+dfsg-3ubuntu2.8 arm64 QEMU full system emulation binaries (arm) ii qemu-system-common 1:2.8+dfsg-3ubuntu2.7 arm64 QEMU full system emulation binaries (common files) ii qemu-utils 1:2.8+dfsg-3ubuntu2.7 arm64 QEMU utilities ProblemType: Bug DistroRelease: Ubuntu 17.04 Package: linux-image-4.10.0-40-generic 4.10.0-40.44 ProcVersionSignature: User Name 4.10.0-40.44-generic 4.10.17 Uname: Linux 4.10.0-40-generic aarch64 AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Nov 24 11:12 seq crw-rw---- 1 root audio 116, 33 Nov 24 11:12 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.20.4-0ubuntu4.8 Architecture: arm64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: CurrentDmesg: Date: Fri Nov 24 11:26:56 2017 IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' MachineType: Cavium ThunderX CRB PciMultimedia: ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: 0 EFI VGA 1 astdrmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-4.10.0-40-generic root=UUID=c5160401-c147-4329-9683-b946ce7d0d37 ro RelatedPackageVersions: linux-restricted-modules-4.10.0-40-generic N/A linux-backports-modules-4.10.0-40-generic N/A linux-firmware 1.164.1 RfKill: Error: [Errno 2] No such file or directory: 'rfkill' SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 12/12/2012 dmi.bios.vendor: American Megatrends Inc. dmi.bios.version: 5.11 dmi.board.asset.tag: To be filled by O.E.M. dmi.board.name: To be filled by O.E.M. dmi.board.vendor: To be filled by O.E.M. dmi.board.version: To be filled by O.E.M. dmi.chassis.asset.tag: To be filled by O.E.M. dmi.chassis.type: 0 dmi.chassis.vendor: Cavium dmi.chassis.version: To be filled by O.E.M. dmi.modalias: dmi:bvnAmericanMegatrendsInc.:bvr5.11:bd12/12/2012:svnCavium:pnThunderXCRB:pvrTobefilledbyO.E.M.:rvnTobefilledbyO.E.M.:rnTobefilledbyO.E.M.:rvrTobefilledbyO.E.M.:cvnCavium:ct0:cvrTobefilledbyO.E.M.: dmi.product.name: ThunderX CRB dmi.product.version: To be filled by O.E.M. dmi.sys.vendor: Cavium ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Affects: qemu-kvm (Ubuntu) Importance: Undecided Status: New ** Tags: apport-bug arm64 regression-proposed uec-images zesty ** Also affects: qemu-kvm (Ubuntu) Importance: Undecided Status: New ** Summary changed: - qemu-kvm in proposed failed with KVM_GET_DEVICE_ATTR failed error + qemu-kvm in zesty proposed failed with KVM_GET_DEVICE_ATTR failed error -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1734326 Title: qemu-kvm in zesty proposed failed with KVM_GET_DEVICE_ATTR failed error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1734326/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
