<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>
