1. A computerized method comprising: communicating by a virtual machine with one or more additional virtual machines to establish membership for a virtual lockstep computing system, wherein each virtual machine is hosted by a node in a network; communicating by the virtual machine with the one or more additional virtual machines to determine a membership configuration for the virtual lockstep computing system, wherein a first virtual machine in the membership configuration is an active machine, and all remaining virtual machines in the membership configuration are standby machines; executing a single step operation by the virtual machine upon obtaining an operational token that includes contents of the single step operation, wherein the operational token is generated by the active machine; and passing the operational token to a next virtual machine in the membership configuration, wherein the operational token is passed between the virtual machine and the additional virtual machines according to the membership configuration.
