Thanks @Babu for the clarifications! I really hope that the qemu patch makes it in v6.0 - then I can better consider picking it up as backport for qemu (already have a bug about that in bug 1921754 - therefore I'm setting the qemu task here as invalid)
The last step I can provide for the kernel bug that this one here is (before the rest of the work is with the kernel Team) is to verify/falsify if that also affects the non-oem linux-generic kernel. There the latest was 5.4.0.71.74 from focal-proposed and the latest already released one is 5.4.0.70.73. 5.4.0.70.73 - failing 5.4.0.71.74 - failing So while the almost-released oem kernel based on 5.10 will cover this - the patch should indeed also be backported to linux-generic and all the other flavours - otherwise Windows (and potentially more) will no more be usable as KVM guest on such Chips (threadrippers, but maybe more AMD chips that are not yet known as well) ** Changed in: qemu (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-oem-5.6 in Ubuntu. https://bugs.launchpad.net/bugs/1915063 Title: Windows 10 wil not install using qemu-system-x86_64 Status in QEMU: New Status in linux package in Ubuntu: Confirmed Status in linux-oem-5.10 package in Ubuntu: Fix Released Status in linux-oem-5.6 package in Ubuntu: Confirmed Status in qemu package in Ubuntu: Invalid Bug description: Steps to reproduce install virt-manager and ovmf if nopt already there copy windows and virtio iso files to /var/lib/libvirt/images Use virt-manager from local machine to create your VMs with the disk, CPUs and memory required Select customize configuration then select OVMF(UEFI) instead of seabios set first CDROM to the windows installation iso (enable in boot options) add a second CDROM and load with the virtio iso change spice display to VNC Always get a security error from windows and it fails to launch the installer (works on RHEL and Fedora) I tried updating the qemu version from Focals 4.2 to Groovy 5.0 which was of no help --- ProblemType: Bug ApportVersion: 2.20.11-0ubuntu27.14 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME DistributionChannelDescriptor: # This is the distribution channel descriptor for the OEM CDs # For more information see http://wiki.ubuntu.com/DistributionChannelDescriptor canonical-oem-sutton-focal-amd64-20201030-422+pc-sutton-bachman-focal-amd64+X00 DistroRelease: Ubuntu 20.04 InstallationDate: Installed on 2021-01-20 (19 days ago) InstallationMedia: Ubuntu 20.04 "Focal" - Build amd64 LIVE Binary 20201030-14:39 MachineType: LENOVO 30E102Z NonfreeKernelModules: nvidia_modeset nvidia Package: linux (not installed) ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: 0 EFI VGA ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-5.6.0-1042-oem root=UUID=389cd165-fc52-4814-b837-a1090b9c2387 ro locale=en_US quiet splash vt.handoff=7 ProcVersionSignature: Ubuntu 5.6.0-1042.46-oem 5.6.19 RelatedPackageVersions: linux-restricted-modules-5.6.0-1042-oem N/A linux-backports-modules-5.6.0-1042-oem N/A linux-firmware 1.187.8 RfKill: Tags: focal Uname: Linux 5.6.0-1042-oem x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: adm cdrom dip docker kvm libvirt lpadmin plugdev sambashare sudo _MarkForUpload: True dmi.bios.date: 07/29/2020 dmi.bios.vendor: LENOVO dmi.bios.version: S07KT08A dmi.board.name: 1046 dmi.board.vendor: LENOVO dmi.board.version: Not Defined dmi.chassis.type: 3 dmi.chassis.vendor: LENOVO dmi.chassis.version: None dmi.modalias: dmi:bvnLENOVO:bvrS07KT08A:bd07/29/2020:svnLENOVO:pn30E102Z:pvrThinkStationP620:rvnLENOVO:rn1046:rvrNotDefined:cvnLENOVO:ct3:cvrNone: dmi.product.family: INVALID dmi.product.name: 30E102Z dmi.product.sku: LENOVO_MT_30E1_BU_Think_FM_ThinkStation P620 dmi.product.version: ThinkStation P620 dmi.sys.vendor: LENOVO To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1915063/+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
