To help this a bit, the two commits I've seen (there might be others) are https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=52297436199dd https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=7204160eb7809
Of those the former is in Focals 5.4 since Ubuntu-kvm-5.4.0-1036.37 The latter is missing. Unless the kernel Team says other commits are needed making this too complex maybe a Focal 5.4 kernel with the second commit backported would allo Aaron to test if this commit is enough on his HW? OTOH the second commit should actually only cache the value, so maybe there are other commits needed anyway, I haven't have more time to look for less obvious commits and the kernel team will be better&faster in doing so anyway. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1950706 Title: VMs running under qemu+kvm can't use xsaves processor feature To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1950706/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
