Currently, all ports attached to an instance must have a fixed IP
address already associated with them ('immediate' IP allocation policy)
or must get one during instance creation ('deferred' IP allocation
policy). However, there are situations where is can be helpful to create
a port without an IP address, for example, when there is an IP address
but it is not managed by neutron (this is unfortunately quite common for
certain NFV applications). The 'vm-without-l3-address' neutron blueprint
[1] added support for these kinds of ports, but until now, nova still
insisted on either a pre-existing IP assignment or deferred IP
assignment. Close the gap and allow nova to use these ports.
Thanks to I438cbab43b45b5f7afc820b77fcf5a0e823d0eff we no longer need to
check after binding to ensure we're on a backend that has
'connectivity' of 'l2'.

- Nova now allows to create an instance with a non-deferred port that has

|
no fixed IP address if the network backend has level-2 connectivity.
