One more comment about the test package version.  Most likely, the package
version will be the same version as the VDSM package version.  The rule we
need to consider is: Should we keep the back compatibility with the VDSM
files? Say allow newer version test package running on older VDSM files? Or
just allow run the same version of test package and VDSM package.

I would prefer the package name 'vdsm-test.rpm' and this package should
unit tests and verification tests.

The test runner should be able to run the full suite of unit tests and
verification tests (with an option to run only unit tests or only
tests).  This can be the same program that we use in the build environment
except that it will set the PYTHONPATH differently to target the installed

If you follow my approach above, you would simply package the whole tests/
directory and no copying would be necessary.

What is the difference between these two types of tests?

Thanks for the idea!  Do you have a sample test for the verification test
Will it be your pipe deadlock test?
