IT teams can shift workloads and allocate networking, memory, storage and processing resources across multiple servers as needed, moving from machine to machine or platform to platform. Because the virtual machines that the hypervisor runs are independent from the physical machine, they are portable.

Portability: Hypervisors allow multiple operating systems to reside on the same physical server (host machine).

Flexibility: Bare-metal hypervisors allow operating systems and their associated applications to run on a variety of hardware types because the hypervisor separates the OS from the underlying hardware, so the software no longer relies on specific hardware devices or drivers.

It is more cost- and energy-efficient to run several virtual machines on one physical machine than to run multiple underutilized physical machines for the same task. Efficiency: Hypervisors that run several virtual machines on one physical machine’s resources also allow for more efficient utilization of one physical server.This makes it easier to provision resources as needed for dynamic workloads. Speed: Hypervisors allow virtual machines to be created instantly, unlike bare-metal servers.There are several benefits to using a hypervisor that hosts multiple virtual machines:
