Subject: [PATCH] qemuBlockStorageSourceGetBackendProps: Report errors on all
switch cases
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Few switch cases returned failure but didn't report an error. For a
situation when the backingStore type='volume' was not translated the
following error would occur:
$ virsh start VM
error: Failed to start domain VM
error: An error occurred, but the cause is unknown
After this patch:
$ virsh start VM
error: Failed to start domain VM
error: internal error: storage source pool 'tmp' volume 'pull3.qcow2' is not translated
