Type 1 (Bare metal): this type of client hypervisor runs directly on the host machine's hardware and serves as the host operating system, providing hardware access to guests via its own drivers. Also, it create a layer above the layer for allocate system resources to all installed virtual machines. [1]
A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine , and each virtual machine is called a guest machine .
Some bare-metal cloud servers may run a hypervisor or containers, e.g., to simplify maintenance or provide additional layers of isolation. [ 4 ] Note that the distinction between these services and the traditional dedicated server offerings is the user's ability to provision infrastructures composed out of multiple servers, a complex network ...
Hyper-V is a native hypervisor developed by Microsoft; it can create virtual machines on x86-64 systems running Windows. [1] It is included in Pro and Enterprise editions of Windows NT (since Windows 8) as an optional feature to be manually enabled. [2]
The result of this is XtratuM 2.0 which is type 1 hypervisor that uses para-virtualization. The para-virtualized operations are as close to the hardware as possible. Therefore, porting an operating system that already works on the native system is a simple task: replace some parts of the operating system HAL with the corresponding hypercalls.
In virtualization, input/output virtualization (I/O virtualization) is a methodology to simplify management, lower costs and improve performance of servers in enterprise environments. I/O virtualization environments are created by abstracting the upper layer protocols from the physical connections .
