Would make sense do the following?

1. Introduce a new tag (e.g. "regression") to mark tests which are 
currently broken due regression bugs

2. Filter those tests out of the regular acceptance jobs

3. Add a new job to run only those tests

  3.1. Use the allow_failure [1] property so that this job won't change 
the overall testing status

Then if a bug is fixed and the test start to pass again, remove the 
"regression" tag. Otherwise if the bug is still present on occasion of 
QEMU release then it is definitively marked to skip.
