People may want to do so to have a dedicated resource for their account and not share the resource with other applications or they may always want to use a specific hardware for their applications. >>or what happen if i have small number of vm on host but there is high >>resource usage on that hosts.

CloudStack currently supports firstfit, user-pod-concentrated, user-dispersing strategies. Using the user-dispersing, spread of VMs of the same account can be achieved. But a generic spread-evenly strategy is not available, please feel free to open a feature request if the above modes do not suit your requirements.

If no such host is present, choose an empty host and dedicate it to the account and use that for further deployments too. o preferred mode: Choose a dedicated host if available, if not it is ok to use a shared host. -----Original Message----- From: Vahric Muhtaryan [mailto:vah...@doruk.net.tr] Sent: Wednesday, November 06, 2013 8:53 AM To: CloudStack SupportMailingList Subject: Planners Hello All , We are discovering compute offering section and couldn¹t understand something about planner. Looks like deployment planner is like intelligent placement on Hyper-v or Vmware DRS but only the placement part. First we can not find explanations of implicitdedicationplanner and bare metal planner , any one know about it ? Second what is planner mode ? What is relation between deployment planner and planner mode ? If we choose deployment planner must we set the planner mode too ? Maybe sounds like stupid but , another thing is we can not imagine some deployment planners, for example if we are running cloud and have a resource, default behaviour should be spread everything almost equal , why people want to put vms depend same account on same pod/cluster or what happen if i have small number of vm on host but there is high resource usage on that hosts. For example KVM do not have an option like vmware drs , how cloudstack handle spread of vms on KVM cluster ? Regards VM
