I'll post a patch to make this a fast failure in the API when trying to attach sriov ports to existing instances. Support for this in the API would require a microversion to indicate when nova actually supports it (if we ever support it) and it would require RPC API version checks on the nova-compute service (and some compute drivers might not support it at all).
