Comment 5 for bug 1808062

One question to last use case which You mentioned. Will nova also somehow restrict VMs to be spawned always in same zone?
What if user will lets say have network which works only in AZ 1, there will be couple of VMs connected to this network and then user will create VM on compute node in different AZ. How neutron should then behave? Do You want to failed to bind such port or bind it properly - and then it will just not have connectivity to other VMs in same network because there will be no tunnel to it?
