One solution would be to dump the XML for the domain and then run

like sed on it to change what ever you want and then update the domain.
Of course that will only work if the domain is stopped.
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.
