<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span style="color:#1F4E79">My use case involves booting up an instance attached to two networks – one having Neutron DHCP service running and one without. Looking within the documentation
[1], I was hoping to use configuration drive to provide IP information for the second interface. But, if I understand correctly, one could theoretically pass any IP information through it; which may or may not match the IP that is assigned to the Neutron port.
I wonder if there is any way the actual IP assigned to the Neutron port is exposed in some way within the VM.</span><o:p></o:p></p>

VM. However this might not be manageable if a user launches numerous VMs since he/she will have to ensure that IPs do not overlap.</span><o:p></o:p></p>
