RH-Commit: [3/12] efe50a2797c679ce6bb5faa423047461a34e6792 (hreitz/qemu-kvm-c-9-s)
|
|
|
|
VMDK's implementation of .bdrv_get_specific_info() returns information
|
|
about its extent files, ostensibly in the form of ImageInfo objects.
|
|
However, it does not get this information through
|
|
bdrv_query_image_info(), but fills only a select few fields with custom
|
|
information that does not always match the fields' purposes.
|
|
|
|
For example, @format, which is supposed to be a block driver name, is
|
|
filled with the extent type, e.g. SPARSE or FLAT.
|
|
|
|
In ImageInfo, @compressed shows whether the data that can be seen in the
|
|
image is stored in compressed form or not. For example, a compressed
|
|
qcow2 image will store compressed data in its data file, but when
|
|
accessing the qcow2 node, you will see normal data. This is not how
|
|
VMDK uses the @compressed field for its extent files: Instead, it
|
|
signifies whether accessing the extent file will yield compressed data
|
|
(which the VMDK driver then (de-)compresses).
|
|
|
|
Create a new structure to represent the extent information. This allows
|
|
us to clarify the fields' meanings, and it clearly shows that these are
|
|
not complete ImageInfo objects. (That is, if a user wants an extent
|
|
file's ImageInfo object, they will need to query it separately, and will
|
|
not get it from ImageInfoSpecificVmdk.extents.)
|
|
|
|
Note that this removes the last use of ['ImageInfo'] (i.e. an array of
|
|
ImageInfo objects), so the QAPI generator will no longer generate
|
|
ImageInfoList by default. However, we use it in qemu-img.c, so we need
|
|
to create a dummy object to force the generate to create that type,
|
|
similarly to DummyForceArrays in machine.json (introduced in commit
|
|
9f08c8ec73878122ad4b061ed334f0437afaaa32 ("qapi: Lazy creation of array
|
|
types")).
