Hi - commit 411a139d84bd34931e0e01d6ed5e48a718392e5d added svm_xsaves_support, but AFAICT support for virtualizing the IA32_XSS MSR on SVM was not merged back from upstream. Commit 864e2ab2b46db1ac266c46a7c9cefe6cc893029d added this support upstream and was a parent of 411a13.
This means QEMU-KVM will report xsaves in CPUID, but IA32_XSS will not be available; guests that expect it to be present when xsaves is enumerated may be surprised. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1887490 Title: [FFe/SRU] Add/Backport EPYC-v3 and EPYC-Rome CPU model To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libvirt/+bug/1887490/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
