[PATCH v3 4/6] admin: Introduce virAdmServer structure

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This is the key structure of all management operations performed on the
daemon/clients. An admin client needs to be able to identify
another client (either admin or non-privileged client) to perform an
action on it. This identification includes a server the client is
connected to, thus a client-side representation of a server is needed.
