@Christian, Yes. This following patch fixes the problem https://lists.gnu.org/archive/html/qemu-devel/2021-03/msg01020.html I saw your ping on the patch. I am not sure why it is not picked up. I am going ping them today.
>If I might ask - how does the kernel fix you referenced interact with this >proposed qemu change? >Assumptions (please correct me): Problem seem to happen when guest tries to access the SPEC_CTRL register to with the wrong settings. The kernel fix avoids writing those values and avoids #GP fault. >1. with the qemu change and using that Rome-v2 it would ask to expose both >features and no more crash (even >on unfixed kernels) Yes. With Qemu patch EPYC-Rome v2 this issue will be fixed. >2. with the kernel fix it will no more crash, even with an unfixed qemu? Yes, That is correct. We need at lease one of these patches to fix this problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1915063 Title: Windows 10 wil not install using qemu-system-x86_64 To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1915063/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
