virtualization programs

The current traditional network may not support the scalability required for large-scale server virtualization and automated configuration in the infrastructure-as-a-service model, but the new network virtual method may even be a network manager hypervisor ), it will change everything. Currently, more than 50% of servers are used as virtual machines. Each virtual machine is connected to the virtual network through a vswitch and network adapter. These

unable to seek common development. It turns out that it's hard to get the user's approval for a virtual storage solution that is only for the storage itself and ignores other IT components. The catalytic effect of server virtualization In stark contrast to the stagnation of storage virtualization, server virtualization is on the dash. More and more users aroun

program is in it, but this solution is relatively passive when the game frequently releases the version, because the image must be updated every time the version is released. Another method is to use a common image to insert game programs and configuration files into the virtual machine when the virtual machine is generated. After the virtual machine is generated and started, the configuration is automatically completed. The fourth point is to make m

to the client, download part of the software based on the user's needs, execute the programs on the client, use their processing power but do not use local storage.　　Benefits: The ability to run applications that cannot be run in shared mode, and to isolate each user's activities to prevent resource constraints. Disadvantage: Use more bandwidth than remote managed desktops, and use more hardware on the server. Performance depends on the quality of th

) or if virtualization is expensive, and to replace them with semi-virtualized operations for direct communication in the virtualization layer.The semi-virtualization of an operating system is to rewrite all code that is incompatible with the semi-virtualized schema. For the Linux kernel, Xen only modifies or adds 2995 lines of code to enable it to run on Xen.Xen

Starting from this chapter, we will enter the core technology chapter of virtualization technology. This article deals only with the basic concepts, which are embodied in the following chapters. The so-called virtualization Technology core technology, refers to how to support the multiple virtual machines on the same physical machine run up. Computer physical resources, in simple terms can be divided into t
