Virtualization and Hypervisor Tasks

Virtualization refers to the abstraction of the physical hardware from the operating system.

Multiple virtual machines with their own virtual hardware components are isolated from each other on one real physical PC.

Various types of hardware and software can be used depending on the application area.

<p>The hypervisor is the virtualization layer on top of which the VMs run. It manages resource allocation of real hardware and the execution of VMs.</p> Signup and view all the answers

<p>Server-based virtualization runs directly on the hardware of the host, is more efficient, and requires fewer resources. Client-based virtualization operates through a remote client.</p> Signup and view all the answers
