Why is VMware GSX considered a type 2 hypervisor?

Because it runs on top of OS. In order for it to be type 1 hypervisor, it has to run on bare metal like ESXI.


What are types of 1 hyper visor and two examples of them?

Type-1, native or bare-metal hypervisors. These are the main software operating on the host computer. All the computer does is run the hypervisor - of course with the virtual machines then running on top of that. Microsoft Hyper-V and VMware ESX/ESXi are examples of a "type-1" hypervisor. Type-2 or hosted hypervisors. These run a base OS like Windows or Linux with a hypervisor application running on top of that. The virtual machines run on top of the hypervisor application. VMware Workstation, and VirtualBox are examples of a "type-2" hypervisor.


Which category of hypervisor does the Microsoft Virtual PC belong?

Type 2


Can Windows 7 access VHDs without the use of a hypervisor?

What is the difference between hosted virtualization and hypervisor-based virtualization?

Both VMware's ESX Server 3.5 and Microsoft's Hyper-V are built using a hypervisorbased architecture. This architecture gives both platforms bare-metal performance that significantly outperforms older hosted virtualization products such as Microsoft Virtual Server 2005 and VMware's Virtual Server 2.0. Hosted virtualization products run the virtualization software on top of the host OS, which introduces additional overhead and a longer code execution path for the virtual machines (VMs) that run in the hosted virtualization environment. In contrast, hypervisor-based products such as ESX Server and Hyper-V are designed to run the hypervisor directly on the system hardware. Although ESX Server and Hyper-V both share a similar hypervisor-based architecture, there are significant differences in the way the products are designed. In both cases, the hypervisor runs directly on the system hardware. However, with ESX Server the hardware drivers are all part of the hypervisor, which significantly increases the size of the hypervisor. In addition, the device drivers are created by the hardware vendors, which introduces third-party code into the hypervisor and limits the hardware that ESX Server supports. Even so, ESX Server is supported on most of the server systems made by all the tier-one vendors, such as HP, Dell, and IBM. Many of these vendors also sell systems configurations with VMware ESX Server preloaded.

It's usually called a hypervisor, or virtual machine monitor.


Why is there no hypervisor for running mac os x on a window pc?

To install Apple's Mac OS X you agree to only use it on hardware built by Apple and so it is illegal to use it on other platforms.
