IMHO, these tests should be left in to check for future problems with bad use of ``--persistent`` instead of config.  Maybe move them under to ``error_test`` would be a good compromise?   Then at least we are sure it really is failing as expected, on the off-chance someday it succeeds.  Better to notice that bug if it ever happens then pretend it never will IMHO.

Another possible complication - Do we still have any RHEL 6.y.z streams (or other distros/versions) that may still need to deal with the behavior-changes inbetweem libvirt-git 1e31b8356047f2275e772f79309e9e94e15dcc6e and 69ce3ffa8d431e9810607c6e00b7cfcc481b491d?  If so, then we probably need to put some (ugly) version-checking logic into this test :S (unless there's a better way).
