FYI - On the Libvirt side the new 3.2 release has the following statement which is - at least - related to the semantics of a host-* cpu specification. That is really a major change which we will unlikely SRU, but pick up naturally when we move to this or a later libvirt version - likely on aa-relase. On top this change still is x86_64 only for now, I'd expect further changes for other architectures down the road (CPU Feat detection is very different per arch anyway, so other arches might go different routes - but this sheds some light on some of the insufficiencies of the old detection at least).
So far just FYI: - qemu: Detect host CPU model by asking QEMU on x86_64 Previously, libvirt detected the host CPU model using CPUID instruction, which caused libvirt to detect a lot of CPU features that are not supported by QEMU/KVM. Asking QEMU makes sure we don't start it with unsupported features. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1673467 Title: [ocata] unsupported configuration: CPU mode 'host-model' for aarch64 kvm domain on aarch64 host is not supported by hypervisor To manage notifications about this bug go to: https://bugs.launchpad.net/nova/+bug/1673467/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
