Shouldn't at least some of the existing tests be converted, then?

Perhaps the macro(s) should be DO_TEST_VERS[ION] or DO_TEST_<ARCH>_VERS instead since DO_TEST runs the test with specific capabilities and this new model runs the test with a specific version for a specific platform. How do or should we enforce that when adding a new test from this point forward that the DO_TEST_CAPS model is chosen over DO_TEST? I suppose there is still value in DO_TEST since one can pick and choose which CAP is needed - although I'll freely admit that's usually a cut-n-paste from some other test and change the name type activity.

I think I have too many questions for an R-b at this point. John -- libvir-list mailing list libvir-list(a)redhat.com https://www.redhat.com/mailman/listinfo/libvir-list
