commit cfce1091d55322789582480798a891cbaf66924e

parallels: Image repairing in parallels_open()
there is a potential pit fall with calling
qemu-io -c "read"
The image is opened in read-write mode and thus could be potentially
repaired. This could ruin testing process.
The patch forces read-only opening for reads. In that case repairing
is impossible.
