Systems and methods for facilitating migration of virtual machines among a plurality of physical machines

A computer readable medium having instructions thereon that when executed provide a method for facilitating migration of virtual machines among a plurality of physical machines, the computer readable media comprising:

• instructions to associate virtual machine with at least one physical resource inaccessible by a first subset of the plurality of physical machines and available to a second subset of the plurality of physical machines, the virtual machine executing on a first physical machine in the second subset of the plurality of physical machines;
• instructions to receive a request to migrate the virtual machine to a second physical machine in the plurality of physical machines;
• instructions to identify a second physical machine in the second subset of the plurality of physical machines;
• and
• instructions to migrate the virtual machine to the second physical machine.
