Hi Paul: I am very glad to do the thing that puts together the practical use cases in which the same VM would benefit from multiple virtual connections to the same network, whatever it takes, I think we should at least guarantee the consistency of creating vms with nics and attaching nics.

I agree its oddly inconsistent (you'll get used to that over time ;-) - but to me it feels more like the validation is missing on the attach that that the create should allow two VIFs on the same network. Since these are both virtualised (i.e share the same bandwidth, don't provide any

I am a beginer of nova, there is a problem which has confused me, in the latest version, it not allowed to create a vm directly with two VIF in the same network, but allowed to add a VIF that it network is same with a existed VIF'network, there is the use case that a vm with two VIF in the same
