Windows Server 2008 Hyper-V Technology Resolution

In the past, enterprise-level virtualization, VMware's ESX Server, Citrix's XenServer and other platforms were almost the most concerned, however, with Microsoft's Hyper-V professional-grade virtualization The introduction of the tool, I believe this pattern will soon change.

Hyper-V is Microsoft's latest server virtualization solution with Windows Server 2008. Compared with Microsoft's own Virtual PC, Virtual Server and other products, there is a significant difference: Hyper-V is on the architecture. Absolutely a breakthrough. The comparison between the two is as follows:

This is a "heavyweight" role, but the code is definitely "lightweight" because the code is only 300 K, and does not contain any third-party drivers, the driver and the new IO shared model are hosted together in the parent partition. Compared to Virtual Server's three-layer conversion, Hyper-V's basic architecture simplifies the number of layers between virtual machines and hardware. This architecture allows virtual machines and hardware to be connected only through a thin layer. Therefore, the execution efficiency of the virtual machine is very high, and the hardware resources can be more fully utilized, so that the performance of the virtual machine system is very close to the real operating system performance.

Hyper-V uses VMbus-based high-speed memory bus architecture. Hardware requests from virtual machines (graphics, mouse, disk, network) can be sent directly to VSP through the VMbus bus to the VSP of the root partition. Call the corresponding device driver, directly access the hardware, without the help of the hypervisor.

Hyper-V System Architecture

Hyper-V uses a microkernel architecture. The underlying hypervisor runs under the highest privilege level. Microsoft calls it ring-1, virtual machine operating system kernel and driver. Running at ring 0, the application runs under ring 3, and this architecture eliminates the need for complex BT (binary privileged instruction translation) technology, which further enhances system security.

perfect support for Linux systems

For a Linux system, business users, the use of Hyper-V is a boon, Because Hyper-V is a good support for Linux, you can install a Linux kernel that supports Xen, so that Linux can know that it is running on Hyper-V, and you can also install Integrated Components designed for Linux, which includes disks and network adapters. The VMbus driver allows the Linux virtual machine to achieve high performance.

In this way, we can centralize all servers including Windows and Linux to the latest Windows Server 2008 platform, make full use of its latest advanced features, and more importantly, Keeping the original Linux key applications will not be affected.
