Suggestion to use nightly

As discussed in oVirt Users mailing list we suggest the user community to use oVirt master snapshot repositories ensuring that the latest fixes for the platform regressions will be promptly available.

This oVirt 4.5.5 release is meant to provide what has been made available in nightly repositories as base for new installations. If you are already using oVirt master snapshot you should already have received this release content.
