Comment 10 for bug 1512908

Actually this is probably the cause of the restarts of libvirt-bin:

        if config('hugepages'):
            ctxt['hugepages'] = True

        ctxt['host_uuid'] = '%s' % uuid.uuid4()
        return ctxt

every time the libvirtd.conf is rendered, libvirt-bin is restart as the uuid is regenerated.
