If you suspect a libguestfs issue, make sure that tracing and/or
debugging are enabled:

http://libguestfs.org/guestfs-faq.1.html#how_do_i_debug_when_using_the_api

Padraig, can libguestfs debug output be captured and logged properly
by Openstack?  If not then we should add a way to do this.  Let's talk
about it tomorrow.
