We probably don't do that, but we really must be running a more
extensive (and slower) test set at least once before every
release.
Maybe some people are running SPEED=slow tests, or even more
extensive test suites like avocado-vt once in a while, but we
need to know who is running them, and when.
Today, the only test set I know people really run and would
surely block a release is "make check [SPEED=quick]".
So, for anybody that runs automated QEMU tests once in a while,
can we know:
* What test cases are you running? Where can we get more
information about the tests you run?
* When do you run them? What triggers a new test run?
Peter, do you have additional tests you run before merging a pull
request? Additional test sets run before tagging a release?
