[PATCH 19/23] tests: qemumonitorjson: Add case for two disks sharing a backing image

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since we have to match the images by filename a common backing image
will break the detection process. Add a test case to see that the code
correctly did not continue the detection process.
