Yes avoid set lets you set the zone,pods,clusters,hosts to be avoided by the planner.

This change is not necessary; it is an optimization. Also, another way is to add a custom planner say DedicatedResourcePlanner that will search for only dedicated resources for the given account. > -----Original Message----- > From: Devdeep Singh [mailto:devdeep.si...@citrix.com] > Sent: Friday, December 21, 2012 2:58 PM > To: cloudstack-dev@incubator.apache.org > Subject: RE: [DISCUSS] Dedicated Resources: Dedicate Pods, Clusters, > Hosts to a domain > > Hi Alex, > > I assume some apis will be added for letting an admin dedicate a > pod/cluster etc to a domain.
