Hypervisors are software programs that act as virtual machines (VMs) and provide a shared virtual environment for multiple users on a single physical machine. These virtual machines run in a controlled and isolated manner, allowing multiple users to share the same operating system, applications, and files. This enables efficient utilization of computing resources and facilitates collaboration among multiple users.
Types of Hypervisors:
Type 1 (bare metal): The hypervisor directly interacts with the underlying hardware, providing full access to the physical machine. This approach offers maximum flexibility and control but is also the most complex and resource-intensive.
Type 2 (hosted): The hypervisor runs as a guest operating system within another operating system. This approach is easier to manage and provides a more efficient and scalable solution.
Xen is a free and open-source hypervisor developed by the Linux Foundation. It is widely used in server and desktop virtualization due to its robust features and support for various platforms.
KVM (Kernel-based Virtual Machine) is a kernel-level virtualization technology included in Linux kernels. KVM provides a lightweight and efficient approach to virtualization, enabling its use within kernel space.
VMware is a commercial virtualization software provider that offers various solutions, including VMware ESXi for large-scale servers and VMware Workstation for desktop virtualization.
Each of these technologies has its own strengths and weaknesses, and the best choice depends on the specific requirements of your application
