Ao tentar efetuar o Live Migration de uma VM (Win7Teste) entre dois hosts Hyper-V (Server1 e Server2) recebia o erro abaixo:
--
Virtual machine migration operation failed at migration source.
Failed to establish a connection with host 'Server1': The credentials supplied to the package were not recognized (0x8009030D).
The Virtual Machine Management Service failed to authenticate the connection for a Virtual Machine migration at the source host: no suitable credentials available. Make sure the operation is initiated on the source host of the migration, or the source host is configured to use Kerberos for the authentication of migration connections and Constrained Delegation is enabled for the host in Active Directory.
[Expanded Information]

Para resolver este "problema", é necessário configurar a delegação, através da ferramenta "Active Directory User and Computers", acessar a conta do computador Server1 por exemplo e delegar os serviços cifs e Microsoft Virtual System Migration Service para o computador Server2, conforme print abaixo (também é necessário configurar a delegação do computador Server2):
Estou levando em conta que nas configurações do Hyper-V já está configurado corretamente o Live Migration, após o procedimento abaixo obtive sucesso no Live Migration.
