We don't really support the NIC ordering in Nova AFAIK. If you look at https://developer.openstack.org/api-ref/compute/?expanded=create-server-detail#create-server we just say for the 'networks' attribute that it's possible to pass multiple UUIDs, either as ports or network IDs but we don't explicitly say that the VM NICs order will be preserved.
Closing it as invalid as I don't think it's something we supported once but feel free to reopen the bug if you know that we previously supported it and we regressed somehow. ** Changed in: nova Status: New => Incomplete ** Changed in: nova Status: Incomplete => Invalid ** Changed in: nova Importance: Undecided => Critical ** Changed in: nova Importance: Critical => Wishlist -- You received this bug notification because you are a member of Yahoo!
