Inside the NVMM accelerator for QEMU

Virtualization allows for the multiplexing of different operating systems on the same hardware. This allows for better utilization of system resources and greater flexibility, enabling common processes such as cloud computing. Virtual Machine Monitors (VMM) A VMM, or a hypervisor, is at the heart of system virtualization. A VMM allows multiple virtual machines to run on a physical machine, much like an operating system allows multiple processes to run on a CPU.
