---------------------------------------

             Summary: VM migration triggered by dynamic scaling is failing
                 Key: CLOUDSTACK-8754
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8754
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
          Components: Management Server
    Affects Versions: 4.5.0, 4.6.0
            Reporter: Koushik Das
            Assignee: Koushik Das
             Fix For: 4.6.0


Steps to reproduce
1. Create a cluster with two hosts, disable one. Since dynamic scaling is supported by XS and Vmware use one of them.
2. Create 2 service offerings (say 'small' and 'big')
3. Exhaust CPU capacity of the enabled host by deploying VMs with SO 'small'.
4. Try scaling up one of the VMs to SO 'big', and make sure it is failing with insufficient capacity.
5. Enable the other host in cluster. Make sure this has enough CPU capacity to accommodate the VM with SO 'big'.
6. Now repeat step 4.

Expected
------------
Since there is no cpu resource left on host, vm should scale up after live migration to another host

Actual
--------
VM scale up failed due to "Received exception while scaling 
com.cloud.utils.exception.CloudRuntimeException: Unable to serialize: com.cloud.vm.VmWorkMigrateForScale@65700a07
