[Qemu-devel] [PATCH] Clarify error msg when open of backing file fails |

This patch clarifies the error message when a problem is encountered
opening a backing file. Currently the only message printed in this case
is:
" qemu: could not open disk image /path/to/image"
This can be confusing if the real error lies in finding the backing file
rather than the primary file.
