Virtio based Transcendent Memory

Virtualization is a technology that lets you run multiple virtual machines on a single physical machine, by sharing the resources of that single computer across the virtual machines. While CPU, I/O devices and other resources are easily shared among the virtual machines, sharing of physical memory is much more difficult. Memory Management mechanisms such as Ballooning and Hotplug Memory are widely used in virtualization systems for efficient utilization of RAM, but digging deep they have their own set of problems. Therefore, memory is increasingly becoming a bottleneck in virtualization.
