Use the latest virt-manager to regenerate the files.
The command line is once again along the lines of
$ virt-install \
--name guest --os-variant fedora29 \
--vcpus 4 --memory 4096 --disk size=5 \
--graphics (none|vnc) \
--print-xml
with some minor tweaks performed afterwards.
This removes a number of inconsistencies between the files,
and makes it so the only differences are actually relevant
either to the architecture and machine type at hand, or to
having graphics rather than being headless.

Right now *-headless and *-graphics tests are using different
quoting styles, which results in the diff between them being
basically useless, whereas we would like it to be possible to
compare these files directly and easily spot the differences.
Convert all *-graphics tests to single quotes, which is the
style libvirt itself uses when formatting XML: this is a fact
that will come in handy later.

In cases when e.g. a new feature breaks upstream behaviour it's useful
to allow users to disable the new feature to verify the regression and
possibly use it as a workaround until a fix is available.

qemu capabilities from the detected bitmap.
This patch introduces the configuration infrastructure to parse the
