![]() Virtual desktops can be hosted on a central server, and end users can access it remotely via the Internet. And because the VMs run by the hypervisor are not dependent on a specific piece of hardware, VMs and workloads can easily be shifted to different servers or platforms as needed.īy separating the hardware and the software, a hypervisor makes desktop virtualization efficient. Hypervisors make it possible to create new VMs instantly, making it simple to allocate resources as needed for dynamic workloads. ![]() ![]() This hypervisor type enables the virtualization of IoT devices, allowing for improved hardware use, enhanced security, and support for multiple OSes. The rise of the Internet of Things (IoT) has led to a third hypervisor type, the embedded hypervisor. They also come with some additional risk, because any system crashes or malware attacks on the host OS then affect the guest VMs as well. While type 2 hypervisors are typically easier to set up and manage than type 1 versions, they do have some latency and performance issues because the host OS still has to manage the physical hardware resources. It is typically used in testing labs or home environments. This hypervisor type does support having multiple guest VMs run on the same host, but it cannot directly access the host hardware and resources. Type 2 hypervisors, sometimes called embedded hypervisors or hosted hypervisors, run as an application within the operating system on the host hardware. Because they have direct hardware access and can directly assign resources, these bare metal hypervisors are highly scalable, can optimize physical resources on the host server, and allow admins to set resource allocation manually. ![]() This hypervisor type is typically found in large-scale or enterprise deployments. In this scenario, the host machine can be used for nothing else but operating the VMs. A type 1 hypervisor acts as a basic OS itself, on which the VMs run. Type 1 hypervisors, also known as native or bare metal hypervisors, run directly on the host machine, with no other software or operating system in between it and the hardware. Hypervisors are generally divided into two types, based on where the hypervisor runs. ![]()
