Did I understand this right to be a combination of roughly 14.04 (Trusty) as base with (probably both through the cloud archive) a libvirt version that appears to closest match with 15.04 (Vivid) and qemu at 15.10 (Wily) level?
Unfortunately I cannot recreate the same results as I only got a fam 10h model 09h host. For that I get the svm flag inside the guest on native Trusty, Vivid, and Wily. However nested is actually broken for all as cpuid function 8000000a seems not implemented in any qemu version (2.0.0 +dfsg-2ubuntu1.18 ... 1:2.3+dfsg-5ubuntu6). I have to check what the G4 type (from fam 16h model 02h) would yield. Just also wondering whether in the case of not dropping svm the kvm module actually loads or also fails on cpuid 8000000Ah. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1494602 Title: qemu-system-x86 nested virtualisation is broken on AMD system To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1494602/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
