Actually, no.  These are writes on the format, not the file itself.  The
monolithicSparse subformat will store everything in a single file,
whereas twoGbMaxExtentSparse will create one file per 2 GB of guest
disk.  So the locations are chosen accordingly to that 2 GB limit ((1)
something somewhere in the first extent, (2) something that wraps around
the first 2 GB limit, so hits extents #0 and #1, and (3) something in
the middle of extent #2.)

(The following qemu-img map call then verifies that it lands in the
different files for twoGbMaxExtentSparse, and that monolithicSparse is
at least indeed sparsely allocated.)

In theory the test could be cloned to only restrict refcount_bits to 16 for the 
0.10 version
but this is probably not worth it given the nature of the test.

[PATCH v2 10/21] iotests: Replace IMGOPTS= by -o

2019-10-15 Thread Max Reitz
Tests should not overwrite all user-supplied image options, but only add
to it (which will effectively overwrite conflicting values).  Accomplish
this by passing options to _make_test_img via -o instead of $IMGOPTS.

For some tests, there is no functional change because they already only
appended options to IMGOPTS.  For these, this patch is just a
simplification.

For others, this is a change, so they now heed user-specified $IMGOPTS.
Some of those tests do not work with all image options, though, so we
need to disable them accordingly.
