Apparently pytest-2.7.3 which we require, isn't available in Fedora 22 , the latest version available there is 2.6.4. Which means we don't support Fedora 22. How much do we care? I guess not that much since 22 will be around only for ~2 months. @tflink, @kparal?

Not only will 22 be around for another month or two but it can't run disposable clients right now with the way that code is written (testcloud relies on a part of the libvirt api that is newer than we thought).
While that could be fixed, I don't see it as terribly important at the moment and suspect that it's not going to happen before f22 goes EOL.
Closing this as 'wontfix', feel free to re-open or continue discussion if there are other opinions
