Public bug reported:

I am using OpenStack queens set up by OpenStack-Ansible.
When I create a VM, it seems to be started and sends DHCP request just before openflow is created.
This will result in a two minutes delay for VM to be accessible.
Test is carried out with Cirros image, as pasted below, VM can't get IP in the first round "sending discover".
Is there a way to add some delay when booting a VM ? Nova will not check openflow before starting the VM ?
