Public bug reported:

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.
