"The doc cited explains how this works with Quantum, but not with Openstack."<br>-As of Folsom, you have the option of using Quantum for networking or Nova Network and I believe Nova network will eventually be deprecated.<br>
<br>"VM1 is shown as being accessible via two VNICs, that implies that their is a Hypervisor that is available by two NICs"<br>-There can be any number of vNICs while using just one physical NIC. Each port created in quantum is a vNIC. However the illustration showed 3 physical NICs all of which could have been on a single hypervisor or each on it sown hypervisor. <br>
<br>Looks like we are deviating from the original question which was posed by Umar. <br><br>Regards,<br>Balu<br><br><div class="gmail_quote">On Thu, Jan 31, 2013 at 11:18 PM, Caitlin Bestler <span dir="ltr"><<a href="mailto:caitlin.bestler@nexenta.com" target="_blank">caitlin.bestler@nexenta.com</a>></span> wrote:<br>

<br>Similar question must be addressed for Cinder and Swift. I am most familiar with Swift, and it really does not address this situation.<br><br><br>Balamurugan V G <<a href="mailto:balamuruganvg@gmail.com" target="_blank">balamuruganvg@gmail.com</a>> wrote:<br>
<br>Perhaps you can use the multiple flat network model shown here:<br><br><a href="http://docs.openstack.org/trunk/openstack-network/admin/content/use_cases_multi_flat.html" target="_blank">http://docs.openstack.org/trunk/openstack-network/admin/content/use_cases_multi_flat.html</a><br>
<br>The TenantC VM1 gets two IPs, one from each net. But in this case each net is in a different subnet.<br><br>May be you can create the nets for the same subet but with diff ranges or even just one IP(/32) and disable DHCP.<br>
<br>Basically the idea is to use multiple vNICs.<br><br>Just throwing at you, I am not entirely sure if it will work, I havent tried it.<br><br>Regards,<br>Balu<br><br><div class="gmail_quote">On Thu, Jan 31, 2013 at 1:51 PM, Umar Draz <span dir="ltr"><<a href="mailto:unix.co@gmail.com" target="_blank">unix.co@gmail.com</a>></span> wrote:<br>

</div>You can associate multiple floating ips to a single instance. Floating ips just create natting entries. Keep in mind that traffic that originates from the server will only come from one of these ips. Also there is no way for the server to determine which ip address the traffic came in on so you will need to do the forwarding at the HTTP layer which has access to the domain name used for the request.<br>
