In order to create virtual instances, you need a management console set up on another machine.

This consists of changing the date and time, IP address, password, etc. Type 1 hypervisors are mainly found in enterprise environments.Īnother type 1 hypervisor may look quite different but they also only allow for simple server configuration. The physical machine the hypervisor is running on serves virtualization purposes only. Type 1 hypervisors are an OS themselves, a very basic one on top of which you can run virtual machines. A Type 1 hypervisor is proven in providing excellent performance and stability since it does not run inside Windows or any other operating system. There is no software or any operating system in between, hence the name bare-metal hypervisor. Type 2 Hypervisor (also known as hosted hypervisors)Ī bare-metal hypervisor (Type 1) is a layer of software we install directly on top of a physical server and its underlying hardware.Type 1 Hypervisor (also called bare metal or native).VMs run simultaneously with the hardware that powers them, and so they are entirely dependent on its stable operation. Or that they are sharing available computing power.

Guest machines do not know that the hypervisor created them in a virtual environment. No matter what operating system you boot up with a virtual machine, it will think that actual physical hardware is at its disposal.įrom a VM’s standpoint, there is no difference between the physical and virtualized environment. Hypervisors emulate available resources so that guest machines can use them. The machine we install a hypervisor on is called a host machine, versus guest virtual machines that run on top of them. Hypervisors create a virtualization layer that separates CPU / Processors, RAM and other physical resources from the virtual machines you create. It abstracts guest machines and the operating system they run on, from the actual hardware. A hypervisor is a crucial piece of software that makes virtualization possible.
