What does Windows 8 built-in Hyper-V mean?

BKJIA Internet headlines in September 14] not long ago, network engineering was still a very complex technology that not only had to be handled by skilled engineers, expensive hardware and mysterious MAC and IP addresses are also important components. Nowadays, all these have become the mainstream content in the job. It is common for children in their teens to switch to user-level routers. Connecting to laptops and accessing the Internet can no longer be referred to as technology. It can only be called pediatrics.

Virtualization will surely become the mainstream through the same process. One day, the children will be able to create and start virtual machines on their laptops. All of this is exactly what Microsoft expects. Just a few days ago, Microsoft's Vyper-V project leader, Matthew John, confirmed a news that had already been hyped up:Microsoft's next-generation desktop operating system will have built-in heavyweight virtualization Components.

"In the creation project of Windows 8, we tried to introduce Hyper-V. This computer virtualization technology already exists in the latest two versions of Windows Server, aiming to provide the same functions for the operating system on the client ."

The current objective situation is that virtualization is not the first time on the mainstream stage of Windows systems-for example, high-end Windows 7 versions include Windows VirtualPC and XP, in essence, virtual machines are used to run Windows XP in Windows 7. Microsoft also holds several other Virtualization Technologies including MED-V. Aside from VMware workstation, Oracle's VirtualBox and other similar products can also be compatible with Windows.

Of course, there are some new content. This is the first time Windows desktop systems have paid attention to it. This allows users to create virtual machines, configure the virtual machines, load the operating system, and start them on the desktop system,All of this is part of the Windows operating system.. This can be said that the mainstream is no longer mainstream, But not more important.

According to John, the version of Hyper-V hypervisor in Windows 8 will be quite complex. It will be able to run a 64-bit operating system in a virtual machine, andSupports 32 processing cores and GB memorySuper Large virtual machine. It also allows desktops to run on virtual machinesEnter sleep statusThe VM process will be automatically paused), and includesDynamic Memory Allocation-- This is similar to VMware Storage vMotion. "With this function, you can transfer the VM storage information from the local disk to another hard disk, USB memory, or remote file sharing system without suspending the normal operation of the VM, "John said. The virtual machine can alsoInitiate access to the outside world through a wireless network adapterIn this process, the Microsoft bridge technology is required to convert the virtual network card on the Virtual Machine and the MAC address between the physical wireless network card in the desktop.

Now let's talk about the inevitable limitations: You must use 4 GB of memory to run 64-bit Windows systems-if you want to run more than five virtual machine systemsMemory size greater than 4 GB. This is probably unacceptable. Software Trusted Platform modules such as BitLocker dependent on specific hardware), or in the processing of gamesSoftware that needs to call GPU will not run well. High-Precision Real-time music mixing production, which is sensitive to latency, will also encounter difficulties in virtual machines.

The main operating system, that is, Windows 8 itself, runs on the virtualization layer after Hyper-V is installed. However, the special feature is that Windows 8 will still be able to directly access all underlying hardware, so applications like BitLocker will still run well outside of the virtual machine. However, John implies that running the master Operating System Based on Hyper-V will also bring some negative results. "……High-Precision applications that are sensitive to latencyDirectly running on the main operating system still causes some problems, "he warned. However, this is also an unavoidable limitation in the virtualization field.

There are still many details that we cannot know. Can I import and convert it to a vmwarevm? What guest operating system does it support? Only Microsoft's own staff, or can every user run various operating systems, including Linux, on Windows 8? In the Hyper-V Server version, you can smoothly introduce CentOS, Redhat Enterprise Linux, SUSE Linux Enterprise Server, and other systems like Microsoft products .) Can enterprise users manage virtual machines in Windows through Microsoft's system center Virtual Machine manager? All these answers will be gradually revealed in the coming months.

When we think of this, we will undoubtedly think that Microsoft has paid a lot of effort. After all, compared with VMware, Microsoft's virtualization industry is not as important in the industry as desktop systems, while Windows operating systems have not played a positive role in promoting it. So, why not integrate Hyper-V virtualization technology with a system that every PC user cannot resist? By introducing Hyper-V to the mainstream stage, each user can start to experience and use it in practice, and all of this is equalOpened up market space in the Business Process of Small and Medium-sized Enterprises. Just think about the reality, that is, every user's desktop system is accurate, but under the System) There are Hyper-V Virtual Devices. What is the great potential for the development of such scale!

Regardless of how Hyper-V develops, it is unlikely to have a big impact on the enterprise-level virtualization field, but we must acknowledge that Hyper-V's current influence is unprecedented. Let's wait and see where it will go.
