Abstract
In embodiments of virtual machine migration, a virtual machine migration system includes a storage array that maintains data. A first host computer includes at least one virtual machine with a virtual drive that is mapped to a logical unit number (LUN) of the storage array, and the LUN corresponds to a LUN mask that associates the LUN with the first host computer. A virtual manager is executable on the first host computer, and is implemented to unmask the LUN to migrate the virtual machine from the first host computer to a second host computer that is configurable as a host of the virtual machine. The virtual manager can log the first host computer out of the LUN and the second host computer can log into the LUN to access the data in the storage array.
