I know that we covered what are type-1 hypervisors way back in Module 1. We have looked at type-2 hypervisors and containers. We will now move on to type-1 hypervisors and we will look at two different ones (this module and Module 6). This page is just being provided as a quick easy way to remind you what a type-1 hypervisor is.
A type 1 hypervisor you will hear often referred to as a 'bare-metal hypervisor'. This is due to the fact that a type 1 hypervisor is installed directly on top of a physical server. A type 1 hypervisor does not require an OS or any software to be installed. A type 1 hypervisor is itself a very basic OS, which provides the ability to run VMs. An enterprise environment will typical use type 1 hypervisors.
Examples of type 1 hypervisors:
KVM (Kernel-Based Virtual Machine)
Red Hat Enterprise Virtualization (RHEV)
Citrix XenServer
Proxmox
Microsoft Hyper-V
VMware vSphere/ESXi
SmartOS
