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.
