<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">During most of the time we have been running OpenNebula 2 and 3 we have been using a
<div>rank based on FREEMEMORY. We are now doing tests using OpenNebula 4.8, in a use case</div>
<div>where we are filling up an empty cloud. FREEMEMORY still in theory should be an accurate value</div>
<div>but the problem is that 6-7 VM's are typically being launched on every SCHED cycle and so a </div>
<div>node that starts out with all of its memory free will end up full of virtual machines in a single cycle.</div>
<div><br>
</div>
<div>Once we got to a full cloud and steady-state it would be fine but when you have 8 VM's </div>
<div>starting at once on an old 8-core node, it takes much longer than it otherwise would.</div>
<div><br>
</div>
<div>Any cheap suggestions to get the default scheduler to do a more horizontal fill?</div>
