<div>I can use nova DifferentHostFilter to achieve VM anti-affinity, by passing in UUID of instance as scheduler hint.</div>
<div> </div>
<div>I am thinking later if I need do live migration or VM Evacuation, can anti-affinity relationship be still honored ?</div>
<div><font face="Times New Roman" size="2"><span style="font-size:11pt;"> </span></font></div>
<div>If no, is there a way to make sure after live migration or VM evacuation, the original anti-affinity relationship can be kept ?</div>
