Subject: [PATCH] conf: Properly parse <backingStore/>
c1c534
c1c534
The terminator would not be parsed properly since the XPath selector was
c1c534
looking for an populated element, and also the code did not bother
c1c534
assigning the terminating virStorageSourcePtr to the backingStore
c1c534
property of the parent.
c1c534
c1c534
Some tests would catch it if there wasn't bigger fallout from the change
c1c534
to backing store termination in a693fdba0111. Fix them properly now.
