Paul, does this friend of a friend have a reproduceable test script for this?

Thanks!

If this is true, I think the issue is not on Neutron side but the Nova
side.
Neutron just receives and handles individual port requests. It has no
notion of the order in which they are attached to the VM.

Can you add the Nova tag to get some visibility to the Nova devs?

    I’m hearing “friend of a friend” that people have looked at the code
    and determined that the order of networks on a VM is not guaranteed.
    Can anyone confirm whether this is true? If it is true, is there any
    reason why this is not considered a bug? I’ve never seen it happen
    myself.____

    To elaborate, I’m being told that if you create some VMs with
    several vNICs on each and you want them to be, for example:____

    __ __

    __1)__Management Network____

    __2)__Production Network____

    __3)__Storage Network____

    __ __

    You can’t count on all the VMs having eth0 connected to the
    management network, eth1 on the production network, eth2 on the
    storage network.____

    __ __

    I’m being told that they will come up like that most of the time,
    but sometimes you will see, for example, a VM might wind up with
    eth0 connected to the production network, eth1 to the storage
    network, and eth2 connected to the storage network (or some other
    permutation.)____
