          By default, the scheduler spreads instances across all hosts
          evenly. Set the <code class="">ram_weight_multiplier</code>

            I can't find any options for nova scheduler to consolidate
            new instances on few hosts instead of 'spreading' them on
            all available hosts.<br>
            <br>
            Simple example: let says we has 10 hosts, each host got 10Gb
            of memory for instances. We has flavors of 3Gb and 5Gb of
            RAM. If we run 20 new instances, they will consume about 6Gb
            per host and we will not able to run new instance with 6Gb
            of RAM (even we have 10*4=40 Gb of free memory on computes,
            none of the hosts has more than 4Gb of memory).<br>
            <br>
            Is any nice way to say 'consolidate' to openstack? Thanks!<br>
