An example method for migrating a live operating system from a first computing device to a second computing device is provided. The example method comprises (a) providing register values of a processor of a first computing device to a second computing device which is in communication with the first computing device; (b) providing contents of a dynamic random access memory, DRAM, of the first computing device to the second computing device; (c) storing the register values in a protected memory of the second computing device, wherein the protected memory is separate from a memory used by the second computing device during normal operation of the second computing device; (d) storing the contents of the DRAM of the first computing device in a DRAM of the second computing device; and (e) loading the register values from the protected memory to registers of a processor of the second computing device.
