Hi,

sorry for the delay. I've posted [1] to disable all the mentioned tests
in CI.

Thanks, I still see random failures in travis:

This disabled the tests only on oVirt CI (OVIRT_CI=1), but it does not
disable on
travis (TRAVIS_CI=1).

Maybe we need to remove remove the default to avoid confusion.

That would add quite a lot of boilerplate I guess. Also, given that wedon't havegerrit-travis integration, it's jenkins that is the source of truth forus. I would rather

leave things as is.
