Abstract:
Systems and methods for live migration of a virtual machine are provided. A migration manager can send a request to a source host machine to migrate a virtual machine to a first destination host machine. The migration manager can determine that the migration of the virtual machine from the source host machine to the first destination host machine has failed. The migration manager can identify an intermediary storage device used during the migration to store a state of the virtual machine. The migration manager identifies a second destination host machine for the virtual machine migration. The migration manager causes the second destination host machine to obtain the state of the virtual machine from the intermediary storage device to migrate the virtual machine to the second destination host machine.
