[virt-tools-list] virt-manager test suite hangs on FreeBSD

[Andrea Bolognani]

In the libvirt-jenkins-ci repo, which contains the configuration for
the CI environment used by libvirt and related project, in the
virt-manager specific configuration we've had this comment for a
while:

  # libxml2's Python 3 bindings don't work properly on FreeBSD,
  # so skip the test suite there for the time being. See
  # https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=224902

and, accordingly, we haven't been running the test suite on FreeBSD.

The bug in question seems to have been fixed in the meantime, so I
figured I'd give it another go. Now the test suite no longer fails
immediately: what happens instead is that it works its way through a
number of tests, and then just hangs there.

I tried iteratively commenting out the test where it was hanging, run
the test suite again, and repeat the process, but that turned out to
take way too long so at some point I just gave up :) Also the various
culprits seemed to be mostly unrelated and I even had to go back
earlier in the file a few times, so it was probably not a good
approach to begin with.

I have no idea how to debug this thing. Can an actual virt-manager
developer jump in? I'll gladly provide guidance on how to set up a
suitable FreeBSD environment - thanks to the libvirt-jenkins-ci
project mentioned above, it's a mostly automated process and
shouldn't take too much time.
