Hypervisor hypervisor strife

But in fact, many of the basic things are crucial in terms of the feasibility of high- capacity. And in many ways defined the strategy of development of complex software virtualization of a particular vendor.

I wrote about this a year or more ago, but that is now remembered having come across this article on here about the architecture Hypre-V, and seeing that there is quite a lively discussion on it (. http://habrahabr. ru/blogs/virtualization/96822 /. ).

On this occasion, remember a couple of his own old ( last year ) for articles about the same subject. I was not there intention to paint the parts (all the same PC Week - this is not the place).

But I would like to draw attention to the fact that there are three types of hypervisors:.

Hypervisor, the first type ( standalone, thin, performed on ... That is a hypervisor itself is in some ways is a minimal operating system. ·.


The second type of hypervisor (host, virtual machine monitor - hosted, Type- 2, V) - a special extra software layer that sits on top of the main host OS, which basically serves as a guest OS management, and emulation and control equipment takes on the host OS. ·.

The hypervisor Hybrid (Hybrid, Type- 1) - Consolidated Version of the first two, in which control functions are performed with a thin hardware hypervisor and a special service deprivilegirovannoy OS running on a thin hypervisor. Typically, the hypervisor runs directly to the processor and system memory, and a service running guest operating systems work with other hardware components.

VMware ESX - Type 1,.
VMware GSX, MS Virtual Server - 2 - type.
Hypre-V, Xen Serber - Hybrid.
