    objects: add HyperVLiveMigrateData stub
    
    This class seems to have been considered a base class, supposed
    to be inherited by driver specific implementation, not being
    registered within the versioned object registry.
    
    Hyper-V does not use this object, so it does not have a driver
    specific implementation. During live migration, a LiveMigrateData
    object will be passed via RPC, which will fail as it can't be
    deserialized.
    
    As a result, this issue breaks Hyper-V live migration.
    
    This patch adds the HyperVLiveMigrateData object in order to avoid
    this issue.

Title:
  Unregistered versioned object breaks Hyper-V live migration

Status in OpenStack Compute (nova):
  Fix Released

Bug description:
  The LiveMigrateData seems to have been considered a base class, supposed to be inherited by driver specific implementations. For this reason, not being registered within the versioned object registry.
      
  Hyper-V does not use this object, so it does not have a driver specific implementation. During live migration, this object
  will be passed via RPC, which will fail as it can't be deserialized.

  As a result, this issue breaks Hyper-V live migration.

  This can easily be fixed by simply registering the LiveMigrateData
  class.
