A hypervisor is a software layer that enables the creation and management of virtual machines (VMs) on a physical host. It allows multiple operating systems to run concurrently on a single physical machine by abstracting the hardware resources. There are two main types of hypervisors:
-
Type 1 Hypervisor (Bare-metal): Runs directly on the hardware without a host operating system. Examples include VMware ESXi, Microsoft Hyper-V, and Xen.
-
Type 2 Hypervisor (Hosted): Runs on top of a host operating system. Examples include VMware Workstation, Oracle VirtualBox, and Parallels Desktop.
Hypervisors manage the allocation of resources such as CPU, memory, and storage to the virtual machines, ensuring isolation and efficient resource utilization.
