Hanna Reitz d570177b50 qemu-img: Change info key names for protocol nodes Currently, when querying a qcow2 image, qemu-img info reports something like this: image: test.qcow2 file format: qcow2 virtual size: 64 MiB (67108864 bytes) disk size: 196 KiB cluster_size: 65536 Format specific information: compat: 1.1 compression type: zlib lazy refcounts: false refcount bits: 16 corrupt: false extended l2: false Child node '/file': image: test.qcow2 file format: file virtual size: 192 KiB (197120 bytes) disk size: 196 KiB Format specific information: extent size hint: 1048576 Notably, the way the keys are named is specific for image files: The filename is shown under "image", the BDS driver under "file format", and the BDS length under "virtual size". This does not make much sense for nodes that are not actually supposed to be guest images, like the /file child node shown above. Give bdrv_node_info_dump() a @protocol parameter that gives a hint that the respective node is probably just used for data storage and does not necessarily present the data for a VM guest disk. This renames the keys so that with this patch, the output becomes: image: test.qcow2 [...] Child node '/file': filename: test.qcow2 protocol type: file file length: 192 KiB (197120 bytes) disk size: 196 KiB Format specific information: extent size hint: 1048576 (Perhaps we should also rename "Format specific information", but I could not come up with anything better that will not become problematic if we guess wrong with the protocol "heuristic".) This change affects iotest 302, which has protocol node information in its reference output.

README

=== This is the QEMU I/O test suite ===

* Intro

This package contains a simple test suite for the I/O layer of qemu.
It does not require a guest, but only the qemu, qemu-img and qemu-io
binaries.  This does limit it to exercise the low-level I/O path only
but no actual block drivers like ide, scsi or virtio.

* Usage

Just run ./check to run all tests for the raw image format, or ./check
-qcow2 to test the qcow2 image format.  The output of ./check -h explains
additional options to test further image formats or I/O methods.

* Feedback and patches

Please send improvements to the test suite, general feedback or just
reports of failing tests cases to qemu-devel@nongnu.org with a CC:
to qemu-block@nongnu.org.
