I think it would make more sense to make the availability-zone argument 
take a comma-separated list of zones.

nova boot --flavor 2 --image ubuntu --availability-zone AZ1,AZ2 vm1

Just to clarify, in a case like this we're talking about using the 
intersection of the two zones, right?  That's the only way that makes 
sense when using orthogonal zones like "hosts with fast CPUs" and "hosts 
with SSDs".
