Robert P. Goldberg classifies two types of hypervisor:[5]
Blazon 1 (or native, bald metal) hypervisors run anon on the host's accouterments to ascendancy the accouterments and to administer bedfellow operating systems. A bedfellow operating arrangement appropriately runs on addition akin aloft the hypervisor.
This archetypal represents the archetypal accomplishing of basic apparatus architectures; the aboriginal hypervisor was CP/CMS, developed at IBM in the 1960s, antecedent of IBM's z/VM. A avant-garde agnate of this is the VMware ESXi, Citrix XenServer or Microsoft Hyper-V hypervisor
Blazon 2 (or hosted) hypervisors run aural a accepted operating arrangement environment. With the hypervisor band as a audible additionalcomputer application level, bedfellow operating systems run at the third akin aloft the hardware.
In added words, Blazon 1 hypervisor runs anon on the hardware; a Blazon 2 hypervisor runs on addition operating system, such as Linux.
Note: Microsoft Hyper-V (released in June 2008)[6] exemplifies a blazon 1 artefact that can be mistaken for a blazon 2. Both the chargeless stand-alone adaptation and the adaptation that is allotment of the bartering Windows Server 2008 artefact use a virtualized Windows Server 2008 ancestor allotment to administer the Blazon 1 Hyper-V hypervisor. In both cases the Hyper-V hypervisor endless above-mentioned to the administration operating system, and any basic environments created run anon on the hypervisor, not via the administration operating system.
