qemu-iotests: add 039 qcow2 lazy refcounts test This tests establishes the basic post-conditions of the qcow2 lazy refcounts features: 1. If the image was closed normally, it is marked clean. 2. If an allocating write was performed and the image was not closed normally, then it is marked dirty. a. Written data can be read back successfully. b. The image file can be repaired and will be marked clean again. c. The image file is automatically repaired when opened read/write.

qemu-iotests: Be more flexible with image creation options qemu-iotests already filters out image creation options that may be present or not in order to get the same output in both cases. However, often it only considers the default value of the option. Cover all valid values instead so that ./check -o name=value can be used successfull for all of them.

qemu-iotests: Adjust test result 039 The moved OFLAG_COPIED check in qcow2_check_refcounts results in a different output from test 039 (mismatches are now found after the general refcount check (as far as any remain)). This patch adjusts the expected test result accordingly. Signed-off-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

block: add BLOCK_O_CHECK for qemu-img check Image formats with a dirty bit, like qed and qcow2, repair dirty image files upon open with BDRV_O_RDWR. Performing automatic repair when qemu-img check runs is not ideal because the bdrv_open() call repairs the image before the actual bdrv_check() call from qemu-img.c. Fix this "double repair" since it leads to confusing output from qemu-img check. Tell the block driver that this image is being opened just for bdrv_check(). This skips automatic repair and qemu-img.c can invoke it manually with bdrv_check(). Update the golden output for qemu-iotests 039 to reflect the new qemu-img check output.
