Abstract
A system and method for migrating a virtual machine and storage may include receiving a request to migrate a virtual machine from a host machine. The system and method include establishing a storage space on a shared storage space and creating an access table and a location table. The access table includes access values indicative of data being accessed. The location table includes location values indicative of a location of the data in the first storage space or a shared storage space. A transfer of data between the first storage space and the shared storage space is done using the access table and the location table. The data is accessible in both the first storage space the shared storage space based on the one or more location values of the location table and access to the data is based on the one or more access values of the access table.
