FWIW, and AFAIUI, in Fedora, the vit-preview repository contains the
packages that will be part of the next to be released Fedora version
(codename 'rawhide'), built for the latest released Fedora version.

This means, right now, it contains the versions of the virt software
that will go in Fedora 21, build on and for Fedora 20. This is
particularly useful, for example, to catch possible regressions, as the
repo docs say themselves:


"Who might be interested in virt preview? It turns out there are four kinds of people in the world.

    1) Users who want things to stay stable and who aren't necessarily expecting new features until they update to the next release of Fedora - these are people with just the updates repo enabled 

    2) Same as (1) but who are willing to help out testing updates for the whole distro in order to catch things before they hit the people in category (1) - these people have the updates and updates-testing repos enabled 

    3) Mostly the same as (1) or (2), but have a specific interest in testing new virt features and are willing to deal with virt regressions - these people enable the updates, updates-testing and preview repos 

    4) People who are interested in helping with Fedora <next> development in general, not just virt - these people run rawhide "
