<p class="MsoNormal" style="margin-bottom:10.0pt"><span style="font-family:"Calibri","sans-serif"">Hi,</span><o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:10.0pt"><span style="font-family:"Calibri","sans-serif"">Nova-compute in Compute nodes send fanout_cast to the scheduler in Controlle Node once every 60 seconds. Configuration file Nova.conf in Compute Node has to
be configured with Management Network IP address and there is no provision to configure Data Network IP address in the configuration file. But if there is any change in the IPAddress for these Management Network Interface and Data Network Interface, then we
have to configure them manually in the configuration file of compute node.</span><o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:10.0pt"><span style="font-family:"Calibri","sans-serif"">We would like to create BP to address this issue of static configuration of IPAddress for Management Network Interface and Data Network Interface of Compute Node
by providing the <b>interface names </b>in the nova.conf file.</span><o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:10.0pt"><span style="font-family:"Calibri","sans-serif"">So that any change in the ipaddress for these interfaces will be updated dynamically in the fanout_cast message to the Controller and update the DB.</span><o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:10.0pt"><span style="font-family:"Calibri","sans-serif"">We came to know that the current deployments are using some scripts to handle this static ipaddress configuration in nova.conf file.</span><o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:10.0pt"><span style="font-family:"Calibri","sans-serif"">Any comments/suggestions will be useful.</span><o:p></o:p></p>
<p class="MsoNormal" style="margin-bottom:10.0pt"><span style="font-family:"Calibri","sans-serif"">Regards,</span><o:p></o:p></p>
