https://bugzilla.redhat.com/show_bug.cgi?id=1201143 The formatdomain.html.in description for <disk> device 'lun' indicates that it must be either a type 'block' or type 'network' with protocol 'iscsi'; however, we did not make that check until domain startup. This caused issues for virt-manager which had an unexpected failure at run time rather config time. This patch adds a check in post part disk device checking for the specific and supported lun types as well as adjusting the test failure to be for parse config rather than run time.
