To test the code you fixed in 656151bf, we need to check the following 1. no 'extra=' or 'root=' in xm.cfg 2. 'extra=' but no 'root=' in xm.cfg 3. 'root=' but no 'extra=' in xm.cfg 4. both 'root=' and 'extra=' in xm.cfg Since all of the existing xmconfig tests have no 'extra=' or 'root=', we've got 1 covered :-). We could be evil and test 2 by adding 'extra=' to an existing paravirt test, e.g. test-paravirt-vcpu. Perhaps less evil would be to add 'extra=' to all the existing paravirt tests, along with <cmdline> in associated .xml file. 3 and 4 need handled a bit differently since the roundtrip xm.cfg to xml to xm.cfg tests will not pass when xm.cfg contains 'root='. The xm.cfg to xml conversion maps 'root=' to <cmdline>, but the reverse maps <cmdline> to 'extra='. The easy solution is to only test the xm.cfg to xml conversion using the DO_TEST_FORMAT macro. E.g attached is a patch that tests xm.cfg to xml conversion of xm.cfg containing both 'extra=' and 'root='. We'd need a similar change for testing only 'root='. Do you have time to tweak the patch to test all conditions and submit a V2? If not I'll get to it. Regards, Jim
