    Description

      We are trying to migrate machine between clusters, ie:
      VM Name: VM-1
      VM CPU: 4
      VM Mem: 4GB
      Disk: First (OS) 50GB, Second (Data) 1932GB ( with 1500 GB of sample data )

      Using XenCenter migration between node within two cluster always fail.

      On XenServer Dundee Beta 2 ( source of migration ) we have following information:
      /var/log/xensource.log

      We have changed memory for Dom0 to 14GB but this change did not resolve the issue.

      Could someone confirm that this problem occurs ?
