Hello!
I still want to clarify one question. Instead of making authentication of oVirt and then impersonation of each user, oVirt can just pass user information inside messages and libvirt at the end can read this user information inside rpc messages (perhaps user login could be written in one of string fields in RPC message, simply login = <...> inside message). Why this (assume that it is possible to implement this for everyone) will not work?

Libvirt authentication happens when a connection is opened - oVirt doesn't
open a connection for each user. So you have to have a way to authenticate
the initial connection, and then authorize individual APIs made on it.
