@Vlad, I had reported this bug previously on https://bugs.launchpad.net/nova/+bug/1885418.
My research with different scenarios showed that the problem is probably related to the latest versions of libvirtd libraries and modules. I did test the previous versions of libvirtd and they worked seamlessly. So this may help you in resolving the issue.
