Abstract
Migration of a virtual machine and associated files to a destination host may be performed. A source host may initiate establishment of a temporary network file share at a destination location of the destination host to provide the source host and the destination host with access to the file share. While the virtual machine is running at the source host, a storage migration and a live migration may be initiated. Using the network file share, the source host may copy the associated files to the destination location. A runtime state of the virtual machine may be copied to the destination host. In a final phase of the migration, the virtual machine at the source host may be stopped, the storage migration may be completed, the copying of the runtime state may be completed, and the virtual machine may be started at the destination host.
