QEMU tries to be as accurate as possible, and so in these test cases will include the filter that is part of the block graph in that backing file string (by virtue of making it a json:{} description of the post-commit subgraph). This makes little sense outside of QEMU, though: Specifically, the throttle node in that subgraph will dearly miss its supposedly associated throttle group object. When starting the commit job, we can specify a custom backing file string to write into said image file, so let’s use that feature to write the plain filename of the backing chain’s next actual image file there. Explicitly provide the backing file so that opening the file outside of QEMU (Where we will not have throttle groups) will succeed.
