[libvirt] [PATCH 5/6] conf: start testing contents of the new backing chain fields

Wed Apr 9 04:35:22 UTC 2014
The testsuite is absolutely essential to feeling comfortable
about swapping the backing chain structure over to a new format.
This patch tests the path settings, and demonstrates that the
correct short name is being passed to the child.
* tests/virstoragetest.c (testStorageChain): Test path.
(mymain): Update expected data.
