1. A multi-hypervisor virtual machine system, comprising: a unitary host machine including one or more processors; at least one unitary virtual machine from a plurality of unitary virtual machines which concurrently relies on each of at least two concurrently available hypervisors to interface with the unitary host machine; and the at least two concurrently available hypervisors, the at least one unitary virtual machine being configured to concurrently communicate with the at least two concurrently available hypervisors to execute on the unitary host machine, wherein a first concurrently available hypervisor from the at least two concurrently available hypervisors controls a first virtual central processing unit of the at least one unitary virtual machine, and a second concurrently available hypervisor from the at least two concurrently available hypervisors controls a second virtual central processing unit of the at least one unitary virtual machine, and wherein the first concurrently available hypervisor is selected for relaying input/output requests generated from the at least one unitary virtual machine running on the second virtual central processing unit to the first virtual central processing unit, such that when outgoing packets from the at least one unitary virtual machine switch back and forth between the first concurrently available hypervisor and the second concurrently available hypervisor, the outgoing packets from the at least one unitary virtual machine are restricted to exit via only the first concurrently available hypervisor.
