The section "Configuring OpenStack Compute" ( <a href="http://docs.openstack.org/trunk/openstack-compute/install/apt/content/compute-minimum-configuration-settings.html">http://docs.openstack.org/trunk/openstack-compute/install/apt/content/compute-minimum-configuration-settings.html</a> ) gives a snippet of an example of the values of parameters in the nova.conf file.</div><div style="font-family: Calibri, sans-serif; font-size: 14px; "><br></div><div style="font-family: Calibri, sans-serif; font-size: 14px; ">The document first lists some common settings in nova.conf file.

However, can someone please help as to the correct setting of "public_interface". And the same setting value would be applicable for the Compute Node, is that right?</span></font></pre><pre><span class="Apple-style-span" style="font-family: Courier; font-size: 12px; ">Thank you very much in advance.</span></pre><pre><span class="Apple-style-span" style="font-family: Courier; font-size: 12px; ">Regards,</span></pre><pre><span class="Apple-style-span" style="font-family: Courier; font-size: 12px; ">Ahmed.</span></pre><pre><font class="Apple-style-span" face="Courier"><span class="Apple-style-span" style="font-size: 12px;"><br></span></font></pre></div></body></html>
