2020-09-07iotests: Test that qcow2's data-file is flushedMax Reitz
Flushing a qcow2 node must lead to the data-file node being flushed as well. Signed-off-by: Max Reitz <mreitz@redhat.com> Reviewed-by: Andrey Shinkevich <andrey.shinkevich@virtuozzo.com> Reviewed-by: Kevin Wolf <kwolf@redhat.com>
2020-04-30qemu-iotests: allow qcow2 external discarded clusters to contain stale dataPaolo Bonzini
Test 244 checks the expected behavior of qcow2 external data files with respect to zero and discarded clusters. Filesystems however are free to ignore discard requests, and this seems to be the case for overlayfs. Relax the tests to skip checks on the external data file for discarded areas, which implies not using qemu-img compare in the data_file_raw=on case. This fixes docker tests on RHEL8.

2020-04-07qemu-img: Report convert errors by bytes, not sectorsEric Blake
Various qemu-img commands are inconsistent on whether they report status/errors in terms of bytes or sector offsets. The latter is confusing (especially as more places move to 4k block sizes), so let's switch everything to just use bytes everywhere. One iotest is impacted.

2020-02-18iotests: Test copy offloading with external data fileKevin Wolf
This adds a test for 'qemu-img convert' with copy offloading where the target image has an external data file. If the test hosts supports it, it tests both the case where copy offloading is supported and the case where it isn't (otherwise we just test unsupported twice). More specifically, the case with unsupported copy offloading tests qcow2_alloc_cluster_abort() with external data files.

2019-04-30tests/qemu-iotests: Fix output of qemu-io related testsThomas Huth
One of the recent commits changed the way qemu-io prints out its errors and warnings - they are now prefixed with the program name. We've got to adapt the iotests accordingly to prevent that they are failing.
