A hypervisor is a software layer that enables multiple virtual machines (VMs) to run on a single physical host. There are two types of hypervisors: Type 1 and Type 2.
Type 1 hypervisors are also known as bare-metal hypervisors because they run directly on the host machine's hardware. They don't require a separate underlying operating system to be installed. Type 1 hypervisors provide better performance and security than Type 2 hypervisors because they have direct access to the host's hardware.
Out of the options provided, the entity that is a Type 1 hypervisor is Citrix XenServer. Citrix XenServer is a popular enterprise-class Type 1 hypervisor that runs directly on the host's hardware. It provides features such as live VM migration, centralized management, and high availability.
Oracle VM VirtualBox, VMware server, and Microsoft Virtual PC are all Type 2 hypervisors. Type 2 hypervisors run on top of a host operating system and are often used for desktop virtualization and testing environments. While Type 2 hypervisors are easier to install and manage than Type 1 hypervisors, they don't provide the same level of performance and security.
