I use "path-to-srcdir/tests/check-block.sh".  It takes about 20 minutes.

There are two issues with check-block:

* tests that require QEMU are skipped (rationale: you might be building
without the x86_64-softmmu target).

* it only runs the "quick" group, but I think we should reverse the
direction and mark slow tests specifically (that would cut about 10
minutes out of the 20).

It's a pity that qemu-iotests doesn't parallelize.  Maybe the harness
could be changed to something more standard.
