Comment 2 for bug 1776189

I'll run less case-bound tests in the form of a full pre-upload regression test on these changes.
Then if safe IMHO can start pushing this to Cosmic and from there consider Bionic SRU.

Note: due to the fact that Cosmic has no "own" qemu version yet the change there will also just modify/extend the Bionic types. Only later on a qemu merge for Cosmic will add cosmic named types.
