[Qemu-devel] [PATCH 0/4] qemu-iotests: Backing file tests

[Kevin Wolf]

This series adds some patches for backing files to qemu-iotests. It is meant to
be applied on top of the recently posted patch introducing test 016.

Adding these tests adds a few failures for me. I'm fairly sure that these are
real bugs though and not problems with the test cases:

* 018 fails for all formats on git master. This is an qemu-img bug. (Fix was
  posted by Akkarit Sangpetch, but corrupted by his mailer - so it's not yet
  included)
* 019 fails for qcow1. Not sure yet why, but likely a qcow bug.
* 020 fails with vmdk. This is a bug of the vmdk driver which stores its
  backing file pointer in the parent image. Will look into fixing this.
