--- fixes: - | Fixes `bug 1670522`_ which was a regression in the 15.0.0 Ocata release. For compute nodes running the libvirt driver with ``virt_type`` not set to "kvm" or "qemu", i.e. "xen", creating servers will fail by default if libvirt >= 1.3.3 and QEMU >= 2.7.0 without this fix. .. _bug 1670522: https://bugs.launchpad.net/nova/+bug/1670522
