qemu-iotests: Test case for backing file deletion Add a test case for trying to open an image file where it is impossible to open its backing file (in this case, because it was deleted). When doing this, qemu (or qemu-io in this case) should not crash but rather print an appropriate error message.

QA output created by 069
=== Creating an image with a backing file and deleting that file ===
Formatting 'TEST_DIR/t.IMGFMT.base', fmt=IMGFMT size=131072
Formatting 'TEST_DIR/t.IMGFMT', fmt=IMGFMT size=131072 backing_file='TEST_DIR/t.IMGFMT.base'
block: Print its file name if backing file opening failed If backing file doesn't exist, the error message is confusing and misleading: $ qemu /tmp/a.qcow2 qemu: could not open disk image /tmp/a.qcow2: Could not open file: No such file or directory But... $ ls /tmp/a.qcow2 /tmp/a.qcow2 $ qemu-img info /tmp/a.qcow2 image: /tmp/a.qcow2 file format: qcow2 virtual size: 8.0G (8589934592 bytes) disk size: 196K cluster_size: 65536 backing file: /tmp/b.qcow2 Because... $ ls /tmp/b.qcow2 ls: cannot access /tmp/b.qcow2: No such file or directory This is not intuitive. It's better to have the missing file's name in the error message. With this patch: $ qemu-io -c 'read 0 512' /tmp/a.qcow2 qemu-io: can't open device /tmp/a.qcow2: Could not open backing file: Could not open '/stor/vm/arch.raw': No such file or directory no file open, try 'help open' Which is a little bit better.
