Every patch I commit gets tested.  I have various tests that I run
depending on which subsystem the patch touches.  Right now, for qcow2, I
don't have nearly enough.  I was hoping that Christoph had something
laying around that I could use since it looks like qemu-io would be a
great harness for qcow2 changes.

It is, definitely. qemu-io is the other part which I needed. But qemu-io alone won't make you happy. It can exercise a lot of code, but it can't tell you if your image is broken in the end. Except for reading back written data, of course, but breakage is often enough more subtle.

But I can write a pretty easy script myself on top of qemu-io so it's no
big deal.  I'm not suggesting holding up development.

Heh, so everyone is writing his own scripts. What would you think about bringing the test cases you use into the repository?

Yeah, I've been wanting to do everything via kvm-autotest but so far, it's not quite up to what I want to use it for. I'll see about cleaning up some of my scripts and posting them. The problem is they rely on custom images.
