I commented on your [11/32] patch about a new line in the end of
qemu_opts_print() being the source of most of io tests breakeage.

Fixing that we still have 073 and 082 breaking. Where 082 shows me
the following:

082                [17:07:48]*** Error in `qemu-img': corrupted double-linked list: 0x00007f69209d2340 ***
