** Description changed: + [Impact] + + * Libvirt (and other management software on top of qemu/kvm) probes + capabilities of the current platform, this breaks on arm with the + current builds making it unable to use KVM on this platform through the + management stack. + + * The fix ensures that probing with -machine none won't break on + platforms with different -cpu support (differs per platform) + + [Test Case] + + * We will run the regression tests to cover any implications to !arm + * The openstack Team will re-run their tests that uncovered the issue to + confirm that execution on arm is not affected by the bug anymore (nor + showing new issues). + + [Regression Potential] + + * The fix only affects "-machine none" cases which are sort of exclusive + for probing which was formerly broken. Therefore there should not be + any regressions, but if any then on non-arm machines in rgard to that + probing. + Any reboot of a machine with libvirt re-probing capabilities would + reveal that - so we should be safe after testing is ok. + + [Other Info] + + * n/a + + --- + bionic ussuri - arm64 (aarch64) QEMU emulator version 4.2.0 (Debian 1:4.2-3ubuntu6.3~cloud0) Error in log is: nova.exception.InternalError: Nova requires QEMU version 2.11.0 or greater This error may be a red herring as this particular version of nova does not display capabilities for aarch64, only armv6l https://pastebin.ubuntu.com/p/JmPsDSwHBv/ If I downgrade to the version in the train cloud-archive (1:4.0+dfsg- 0ubuntu9.8~cloud0) then nova-compute service starts - this problem is not present in focal, which also has version also has 1:4.2-3ubuntu6.3
