This helps to ensure that each virtual machine has the resources it needs to run efficiently. Resource Allocation: Hypervisors provide a way to allocate resources such as memory and CPU to virtual machines.In addition to creating virtual machines, modern hypervisors are also capable of providing additional features such as live migration between different hosts without any interruption in service - meaning that if one machine fails another one can take its place immediately without any downtime - resource pooling across multiple servers thus allowing greater utilization rates - improved security via isolation between guest VMs running atop them - support for hot swapping of devices - snapshotting capabilities so that users can quickly revert back any changes they make while testing something new in their environment, etc. Examples here could include Intel TXT (Trusted Execution Technology), AMD SVM (Secure Virtual Machine), etc. Popular examples of this type include VMware Workstation Player/Pro/Enterprise, Oracle VirtualBox, Parallels Desktop for Mac Pro Edition, etc.Īpart from these two main types there exist also some advanced variants like embedded hypervisors (or microkernels) where only minimalistic libraries are used in order to create more secure virtualized environments inside small devices like routers or IoT gateways which can be beneficial when dealing with malware threats or cyber-attacks from outside sources.

Type 2 hypervisors are essentially applications that are installed over an existing operating system like Windows or Linux as 'guests.' This type requires fewer resources such as CPU cycles but usually provides less performance than native solutions due to increased overhead required by the existing OS infrastructure needed to communicate with guest VMs running on it. Some popular examples of this type include VMware ESX/ESXi, Microsoft Hyper-V Server, Citrix XenServer, Oracle VM Server for SPARC (LDoms), IBM PowerVM (LPARs), KVM, etc. In other words, this type of hypervisor 'owns' the entire stack including its own operating system allowing it to provide better performance than a hosted hypervisor. Type 1 is installed directly on top of the physical server’s hardware and provides direct access to all server components such as memory, storage, and CPU.

Hypervisors are often divided into two categories: Type 1 (native or bare-metal) and Type 2 (hosted). A hypervisor allows several guest virtual machines to run concurrently on a single host machine by isolating their operating system environments from each other and sharing the underlying resources of the hardware platform.

It is the technology responsible for running multiple operating systems on a single physical host computer. A hypervisor is a specialized piece of software, firmware, or hardware that creates and runs virtual machines.
