<span>My goal is to assigne bigger instances (from bigger flavors) to BigGroup and </span><span>smaller instances to SmallGroup.</span></div><div style="font-style:normal;font-size:16px;background-color:transparent;font-family:times new roman, new york, times, serif;">
<span>I tried the "AggregateInstanceExtraSpecsFilter" filtering with assigning different keys to instances and making aggregated hosts (http://docs.openstack.org/folsom/openstack-compute/admin/content/host-aggregates.html), but didn't work and all the instance boots will end up to error.</span></div>

bigger nodes for weighting?</div><div style="font-style:normal;font-size:16px;background-color:transparent;font-family:times new roman, new york, times, serif;"><br></div><div style="font-style:normal;font-size:16px;background-color:transparent;font-family:times new roman, new york, times, serif;">
