Re: [libvirt] [PATCH 05/19] tests: qemublock: Add test for bitmap detection

Test the extraction of data about changed block tracking bitmaps. The first test case adds a simple scenario of multiple bitmaps in one layer. The test data will be also later reused for testing the code that determines which bitmaps to merge for an incremental backup.
