      What were you trying to do that didn't work?
      QE found a BSOD in netkvm & virtio_win_pvpanic whql tests using qemu-kvm-9.1.0-11.el10 on the ws2025 WHQL tests with prewhql271. The BSOD frequently happens when the HLK client is installed for a while. The reproduction does not need to run any netkvm tests. We just need to wait a second for the HLK client to be installed, and then BSOD happens with 100% on ws2025.

      Please provide the package NVR for which bug is seen:

      • CPU=AMD EPYC 7313 16-Core Processor
      • virtio-win-prewhql-0.1-271
      • kernel-6.12.0-41.el10.x86_64
      • edk2-ovmf-20241117-1.el10.noarch
      • swtpm-0.9.0-4.el10.x86_64
      • qemu-kvm-core-9.1.0-10.el10.x86_64

      How reproducible:
      100%

      Steps to reproduce
      1. Boot a Win2025 VM using qemu-kvm-9.1.0-11.el10.
      2. Install the HLK client(eg: \\<your_hlk_server>\HLKInstall\Client\setup.bat).
      3. Wait for a while for the HLK client to be installed.

      Expected results
      Normal to boot.

      Actual results
      BSOD, Stop code is "HYPERVISOR ERROR"

      Additional Notes:

      • My "svm|vmx" CPU flag is always open.
      • Even though one test case has passed, BSOD still happens.
      • AFAIK, Xiaoling's whql test does not encounter this issue even using qemu-kvm-9.1.0-11.el10.

            yuri.benditovich Hi Yuri,

            There is no BSOD in the ws2025 whql guests on the AMD host with the qemu-kvm-core-9.1.0 11 build.

            It looks like this problem has just gone.

            I only tested it once and will continue trying to see whether it's disappeared.

            yuri.benditovich Hi Yuri,

            I tested it again in my AMD host with the qemu-kvm-core-9.1.0 11 build. The result was that I passed without BSOD, and I don't know why.

            Let me test the ws2025's BSOD problem, which still happens in this host again. I will remove "regression as Yes" if BSOD still exists.

            ===

            QE still needs to do several things to ensure the CPU model and Intel-IOMMU is correctly configured. This requires testing on a non-AMD machine to confirm whether this is a new valid product bug or a duplicate issue. cc qizhu@redhat.com

            yuri.benditovich Hi Yuri,

            I hit the BSOD again on my INTEL(R) XEON(R) GOLD 6526Y host. I want to attach the dump file to this Jira issue in advance to confirm if there is some valuable information in it. However, according to the discussion with our team members in our QE group meeting, I still need to fix/add more qemu-kvm cmd line configurations to confirm this is an actual product bug, such as CPU model, intel-iommu, etc.  cc qizhu@redhat.com

            Q: Please try to run qemu-kvm-9.1.0-11.el10 without hv_tlbflush

            A: Without hv_tlbflush, BSOD still happens in qemu-kvm-9.1.0-11.el10.

            Q: Is it possible to say in which exactly netkvm test the BSOD happens?

            A: The reproduction doesn’t need to run any netkvm tests. We need to wait a second for the HLK client to be installed, and then BSOD happens with 100% on ws2025.

            yuri.benditovich Hi Yuri,

            After debugging, I found that Jira is not directly related to the Qemu-kvm version, but VBS is true. 

            ==

            The following are some tries I did a few days ago. Let me list them for your reference.

            Win11: The netkvm tests could not run on qemu-kvm-9.1.0-11.el10 with VBS opened. But it can run on qemu-kvm-9.1.0-10.el10, and VBS opens.

            Win10.x86_64: The netkvm tests could run on qemu-kvm-9.1.0-10.el10 with VBS opened. Some test cases are still running and have not hit BSOD for now.

            Win2022: The netkvm tests could not pass on qemu-kvm-9.1.0-11.el10 and qemu-kvm-9.1.0-10.el10 with VBS opened. BSOD happens.

            Win2025: The netkvm tests could not pass on qemu-kvm-9.1.0-11.el10 and qemu-kvm-9.1.0-10.el10 with VBS opened. BSOD happens.

            Win2016: The netkvm tests could pass on qemu-kvm-9.1.0-10.el10 (VBS function is not supported on this OS version).

            Win10.i386: The netkvm tests could pass on qemu-kvm-9.1.0-10.el10 (VBS function is not supported on this OS version). Many test cases failed, but they were driver problems. I will open another Jira to report them.

            Win2019: Still in TODO status, but QE does not want to enable the VBS function because the VBS is not supported on this OS version.

            ==

            The above tests were all run on a HOST's CPU=AMD EPYC 7313 16-Core Processor.

            But I have run Win2025 and Win2022 on a HOST's CPU=INTEL(R) XEON(R) GOLD 6526Y, and the problem of this Jira still exists. cc yvugenfi@redhat.com qizhu@redhat.com

We need to wait a second for the HLK client to be installed, and then BSOD happens with 100% on ws2025. === yuri.benditovich Hi Yuri, After debugging, I found that Jira is not directly related to the Qemu-kvm version, but VBS is true.  == The following are some tries I did a few days ago. Let me list them for your reference. Win11: The netkvm tests could not run on qemu-kvm-9.1.0-11.el10 with VBS opened. But it can run on qemu-kvm-9.1.0-10.el10, and VBS opens. Win10.x86_64: The netkvm tests could run on qemu-kvm-9.1.0-10.el10 with VBS opened. Some test cases are still running and have not hit BSOD for now. Win2022: The netkvm tests could not pass on qemu-kvm-9.1.0-11.el10 and qemu-kvm-9.1.0-10.el10 with VBS opened. BSOD happens. Win2025: The netkvm tests could not pass on qemu-kvm-9.1.0-11.el10 and qemu-kvm-9.1.0-10.el10 with VBS opened. BSOD happens. Win2016: The netkvm tests could pass on qemu-kvm-9.1.0-10.el10 (VBS function is not supported on this OS version). Win10.i386: The netkvm tests could pass on qemu-kvm-9.1.0-10.el10 (VBS function is not supported on this OS version). Many test cases failed, but they were driver problems. I will open another Jira to report them. Win2019: Still in TODO status, but QE does not want to enable the VBS function because the VBS is not supported on this OS version. == The above tests were all run on a HOST's CPU=AMD EPYC 7313 16-Core Processor. But I have run Win2025 and Win2022 on a HOST's CPU=INTEL(R) XEON(R) GOLD 6526Y, and the problem of this Jira still exists. cc yvugenfi@redhat.com qizhu@redhat.com   ===   Regards, Wecom

            1. Please try to run qemu-kvm-9.1.0-11.el10 without hv_tlbflush
            2. Is it possible to say in which exactly netkvm test the BSOD happens?
