[PATCH v13 03/11] qcow2_format.py: change Qcow2BitmapExt initialization method

There are two ways to initialize a class derived from Qcow2Struct: 1. Pass a block of binary data to the constructor. 2. Pass the file descriptor to allow reading the file from constructor. Let's change the Qcow2BitmapExt initialization method from 1 to 2 to support a scattered reading in the initi

[PATCH v13 10/11] qcow2_format.py: support dumping metadata in JSON format

[PATCH v13 01/11] iotests: add test for QCOW2 header dump

The simple script creates a QCOW2 image and fills it with some data. Two bitmaps are created as well. Then the script reads the image header with extensions from the disk by running the script qcow2.py and dumps the information to the output. Other entities, such as snapshots, may be added to the t
