Hypervisor runs directly on underlying host system.It is also known as “Native Hypervisor” or “Bare metal hypervisor”.It dose not require any base server operating system.It has direct access to hardware resources.Examples of Type 1 hypervisors include VMware ESXi, Citrix XenServer and Microsoft Hyper-V hypervisor. It furthermore separates Virtual Machines (VMs) from each other logically, so even if one OS crashes for some reason, the other VMs can function unhindered. The top reviewer of Citrix Hypervisor writes "The ability to move a VM while it is still running and continue doing maintenance work is a big advantage". The already present OS manages the requirements for memory, storage, and network resources. 2. Although this is not the case for more straightforward scenarios, Hosted Hypervisors are still popular for personal use and SMBs. It’s implemented on computer hardware as code embedded in a system’s firmware or as a software layer. The native hypervisors are a more secure option.
