ABSTRACT:
One or more computer systems, a carrier medium, and a method are provided for transferring a virtual machine between computer systems. In one embodiment, a first computer system and a second computer system are coupled to communicate at least intermittently. In response to a request, a first virtual machine executing on the first computer system is transferred to the second computer system. For example, in one embodiment, the first computer system suspends the first virtual machine to an image, which is transmitted to the second computer system. The first virtual machine is resumed on the second computer system from the image. In one particular implementation, the first computer system may suspend the image to a first storage device accessible to the first computer system, and the image may be copied over a network to a second storage device accessible to the second computer system.
