Abstract
A computing cloud comprising at least one computing node having a Virtual Machine (VM) running on a user level. A plurality of additional computing nodes, each node having a Hypervisor with the highest privilege level, a Virtual Machine Monitor (VMM) running with no higher privileges than the Hypervisor, and a plurality of Virtual Machines (VMs) running on a user level. Each node has a Primary operating system (POS) running within the one of its VMs. The POS has direct access to hardware devices of the corresponding computing node. The other VMs use the corresponding POS of its node to access the hardware devices.
