I disagree that this is dead code.  Two commits add a regression test
of v2v on the opensuse guests (as we already have for Fedora and other
guests), and one of those commits is this patch which is needed for
that regression test to work.  Regression tests are a good thing -
they run on every release (as indeed I am running them right now) and
ensure that other aspects of the code don't regress because of some
unintentional change.

Also I don't think the patch is incorrect, even if it is only
applicable for certain types of "just installed / never booted" guests
that we probably wouldn't see outside of the regression testing.
