<p class="MsoNormal"><span style="color:#1F497D">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Motivation behind this requirement is “ to achieve VM prefix aggregation using routing protocol ( BGP/OSPF)”.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">So that prefix advertised from cloud to upstream will be aggregated.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I do not have idea how the current scheduler is implemented.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">But schedule to maintain some kind of the ‘Network to Node mapping to VM” ..<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Based on that mapping to if any new VM getting hosted to give prefix in those Nodes based one input preference.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">It will be great help us from routing side if this is available in the infrastructure.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I am available for review/technical discussion/meeting.

<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal">I have one of the basic question about the Nova Scheduler in the following below scenario.<o:p></o:p></p>
<p class="MsoNormal">Whenever a new VM to be hosted is there any consideration of network attributes ?
<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in">Example let us say all the VMs with 10.1.x is under TOR-1, and 20.1.xy are under TOR-2.<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in">A new CN nodes is inserted under TOR-2 and at same time a new tenant VM needs to be hosted for 10.1.xa network.<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in"> <o:p></o:p></p>
<p class="MsoNormal">Then is it possible to mandate the new VM(10.1.xa) to hosted under TOR-1 instead of it got scheduled under TOR-2 ( where there CN-23 is completely free from resource perspective ) ?
<o:p></o:p></p>
<p class="MsoNormal">This is required to achieve prefix/route aggregation and to avoid network broadcast (incase if they are scattered across different TOR/Switch) ?
<o:p></o:p></p>
