Comment 6 for bug 1697729

In theory this could exist back to Xenial as well (the double cleanup is there), but the cleanup code was changed later which could affect the race. Also we so far got no reports on this pre Ocata/Zesty so for now do not push further back than Zesty.
From the Upstream/Redhat Tests it was also confirmed that pre libvirt 2.4 it is not reproducible, that confirms our timeline of Zesty/Artful, but not further back for now.
