Expected results: No error was happen when executing cron job 'python /usr/share/rhn/virtualization/poller.pyc'. Additional info:
I am not sure about the functional impact, at worst this can break any RHN usage.

The directory was created at runtime, and that failed. Now we create the dir at build time.
This was actually already included in a build, because we respun RHEV-H, thus moving back to 3.5.0.
