Comment 17 for bug 1890881

There are a bunch of Fixes for this commit in 5.1 and some dependencies to those.
These we need to pull in as well here - which makes it even less SRUable :-/

I guess we will fix it in Groovy (20.10) and users that rely on this valid but rare use case can use groovy or -later on- the Ubuntu Cloud Archive [1] that will backport the qemu of groovy together with Openstack Victoria then.
