See http://www.infradead.org/rpr.html From: David Woodhouse If a corresponding NIC configuration was found, it will have a MAC address already assigned, so use that. Else, generate and assign a default one. Using qemu_find_nic_info() is simpler than the alternative of using qemu_configure_nic_device() and then having to fetch the "mac" property as a string and convert it.
