Hypervisor or virtual machine monitor (VMM) is a piece of computer software. It allows to run multiple different operating systems.
Nested virtualization is guest operating system is itself a hypervisor that virtualizes not just processors and memory but also storage, networking hardware assists, and other resources. The VM hypervisor represents the first implementation of practical nested virtualization with hardware assists for performance. There are a number of hypervisors support nested virtualization though not as efficiently […]

The memory balloon driver (vmmemctl) collaborates with the server to reclaim pages that are considered least valuable by the guest operating system. The driver uses a proprietary ballooning technique that provides predictable performance that closely matches the behavior of a native system under similar memory constraints. This technique increases or decreases memory pressure on the […]
