<div dir="ltr">Hello fellow Ops-minded stackers!
<div><br>
</div>
<div>I understand OpenStack uses scheduler logic to place a VM on a host to ensure the load is balanced across hosts. My 64 million dollar question is: Has anyone identified a way to monitor capacity across all hosts on an ongoing basis and automatically live
migrate VM's as needed to ensure hosts resource consumption is balanced over time?</div>
<div><br>
</div>
<div>It seems the scheduler addresses capacity at the time of instantiation but there's nothing that addresses optimal usage AFTER the VM is initially placed.</div>
<div><br>
</div>
<div>Thoughts/experiences?</div>
