I was having this exact same problem after a recent rebuild of my system.
Qemu was working just fine before the rebuild, but gave me that error after
the rebuild no matter what I tried.  It drove me crazy for several days, and
I was half-way through writing a message to this very list for help, when I
had an idea.

Turns out that I had added the few accounts I use on my worksatation in a
different order, so the file permissions on the restored VM images were not
writable by the user who was running qemu.  I ran chmod a few times and qemu
was happy again.

It may be a permissions problem.
