Finally I'm able to test on a Threadripper myself now. Note: In regard to the commit that Babu identified - I'm on kernel 5.10.0-1020-oem so that patch would be applied already. I need to find an older kernel to retry with that as well
(on that new kernel) I did a full Win10 install and it worked fine for me. In regard to CPU types (for comparison) I got qemu 1:4.2-3ubuntu6.15 / libvirt 6.0.0-0ubuntu8.8: <mode name='host-model' supported='yes'> <model fallback='forbid'>EPYC-Rome</model> <vendor>AMD</vendor> <feature policy='require' name='x2apic'/> <feature policy='require' name='tsc-deadline'/> <feature policy='require' name='hypervisor'/> <feature policy='require' name='tsc_adjust'/> <feature policy='require' name='stibp'/> <feature policy='require' name='arch-capabilities'/> <feature policy='require' name='ssbd'/> <feature policy='require' name='xsaves'/> <feature policy='require' name='cmp_legacy'/> <feature policy='require' name='invtsc'/> <feature policy='require' name='amd-ssbd'/> <feature policy='require' name='virt-ssbd'/> <feature policy='require' name='rdctl-no'/> <feature policy='require' name='skip-l1dfl-vmentry'/> <feature policy='require' name='mds-no'/> <feature policy='require' name='pschange-mc-no'/> </mode> With a more recent qemu/libvirt it isn't much different for this chip (there recently were some Milan changes, but those seem not to matter for this chip). qemu 1:5.2+dfsg-9ubuntu1 / libvirt 7.0.0-2ubuntu1 <mode name='host-model' supported='yes'> <model fallback='forbid'>EPYC-Rome</model> <vendor>AMD</vendor> <feature policy='require' name='x2apic'/> <feature policy='require' name='tsc-deadline'/> <feature policy='require' name='hypervisor'/> <feature policy='require' name='tsc_adjust'/> <feature policy='require' name='stibp'/> <feature policy='require' name='arch-capabilities'/> <feature policy='require' name='ssbd'/> <feature policy='require' name='xsaves'/> <feature policy='require' name='cmp_legacy'/> <feature policy='require' name='invtsc'/> <feature policy='require' name='amd-ssbd'/> <feature policy='require' name='virt-ssbd'/> <feature policy='require' name='rdctl-no'/> <feature policy='require' name='skip-l1dfl-vmentry'/> <feature policy='require' name='mds-no'/> <feature policy='require' name='pschange-mc-no'/> </mode> I wasn't able to crash this setup with an old (18.04) nor a new 21.04) Ubuntu guest. Installing Win10 worked fine for a while and didn't break as reported. But the setup I have goes through triple ssh-tunnels and around the globe - that slows things down a lot :-/ This is how far I've got: 1. start up the install 2. select no license key -> custom install -> it started copying files 3. it goes into the first reboot After this the latency kills me and virt-manager starts to abort the installation. So far I did not hit (https://launchpadlibrarian.net/529734412/security.png) as reported by David. @David - did this already pass the critical step for you, how early or late in the install did you hit the issues. As I said I'll probably need to find an older kernel anyway (to be before the commit that Babu referenced) -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1915063 Title: Windows 10 wil not install using qemu-system-x86_64 Status in QEMU: New Status in qemu package in Ubuntu: Confirmed 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
