<div>We would love to have something like that as well.</div>
<div><br>
</div>
<div>However, to do it in openstack would mean that something would have to gather/monitor the health of the HV's and not only disable new provisions but kick off/monitor the migrations off the host and onto the new chosen destinations . Also, due to the fact
that some migration may never complete (dirtying pages faster than you can copy them) it would have to have some smarts to select the vm's that have the higher chance of being migrated.</div>

<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>
