Another one is to use the virt-xml tool to update only the part you need: virt-xml <domain> --edit --network network=default,mac.address='<new_mac>' ^This would require you to restart the domain for the change to take effect. virt-xml <domain> --update --remove device --network mac.address='<old_mac>' virt-xml <domain --update --add-device --network network=default,mac.address='<new_mac>' ^This would not, because it translates to hot-unplug and hot-plug respectively. Just an alternative to using sed. Regards, Erik
