Abstract

A method commences upon receiving a request to migrate a subject virtual machine from a first computing machine to a second computing machine. An agent determines which storage assets are used by the subject virtual machine. The agent collects volume metadata pertaining to the storage assets and clones volume metadata from the first computing machine to the second computing machine. The data blocks comprising the volumes are not moved to the second computing machine until after migrating the subject virtual machine from the first computing machine to the second computing machine. After starting the migrated instance of the subject virtual machine, the migrated instance mounts volumes using the cloned metadata. The first computing machine and the second computing machine cooperate by processing storage asset block requests issued by the migrated virtual machine. Data blocks comprising the volume are moved on demand. The migrated virtual machine can be migrated yet again.
