not enough free memory on one host of the cluster

[Nikita Gubenko]

Hi
I'm testing some overprovisioning cases. I have two XenServer hosts with
lots of VMs on each.
When I try to upgrade resources on the VM on the host that doesn't have
enough free memory for it and try to start it I get

Task failed! Task record: uuid: 0582f281-5a54-27cd-ba23-a4edf60312f4
           nameLabel: Async.VM.start_on
     nameDescription:
   allowedOperations: []
   currentOperations: {}
             created: Thu Apr 25 00:29:34 MSK 2013
            finished: Thu Apr 25 00:29:34 MSK 2013
              status: failure
          residentOn: com.xensource.xenapi.Host@234582ee
            progress: 1.0
                type: <none/>
              result:
           errorInfo: [HOST_NOT_ENOUGH_FREE_MEMORY, 8659140608, 6721728512]
         otherConfig: {}
           subtaskOf: com.xensource.xenapi.Task@aaf13f6f
            subtasks: []

This is normal behavior, but CS doesn't try to start this VM on the second
host of the cluster which has enough free memory. OfferHA option is enabled.

Is there a way to fix this or am I missing something?
