[libvirt] PATCH 0/4: Openvz bridge support & related patches

[Daniel P. Berrange]

This patch series is derived from Anton Protopopov /Evgeniy Sokolov
bridge device patches. It first does some generic refactoring of MAC
address handler in all drivers, then adds code to extract openvz version
number, then does network config, and finally does filesystem config.
