Not sure how much of this you caught in IRC so adding it here as well.
I haven't done much specific debugging of libguestfs with OpenStack. I
just know that OpenStack as deployed by devstack
(https://review.openstack.org/#/c/70546/ specifically tests the
recommended libguestfs install but it didn't work without that change
either) would fail tempest testing when using libguestfs. The bug
could be anywhere in the stack. I have unabandoned that change so that
we can do more debugging with it. Feel free to push new patches to it
that run the libguest-test-tool as suggested. I hope to eventually get
to it but am busy with other things this week and possibly next as
OpenStack is going through feature freeze. Hope this helps and I will
do my best to get the info you need.
