A type-1 hypervisor is a software layer that sits between the guest operating systems and system's hardware.[1] It presents a virtual running environment to an operating system. An example of a common hypervisor is Xen.[2] A type-1 hypervisor operates at a level below the operating system and could be designed with Rootkit functionality to hide its existence from the guest operating system.[3] A malicious hypervisor of this nature could be used to persist on systems through interruption.
