This patch series introduces the image fuzzer, a tool for stability and reliability testing. Its approach is to run large amount of tests in background. During every test a program (e.g. qemu-img) is called to read or modify an invalid test image. A test image has valid inner structure defined by its format specification with some fields having random invalid values.
Patch 1 contains documentation for the image fuzzer, patch 2 is the test runner and remaining ones relate to the image generator for qcow2 format.
