[libvirt] [PATCH 0/6] Clarify semantic of virDomain(G|S)et*Parameters functions

This series was inspired by the discusion about invalid argument checking in the public API and the unclear semantic of this functions. https://www.redhat.com/archives/libvir-list/2011-May/msg01105.html Clarify that the getter functions don't allow to obtain a subset of the parameters. You can only get all at once. Clarify that the setter functions can set a subset of the parameters. Matthias
