Definition
Virtual machine by means of simulation software with a complete hardware system, operating in a completely isolated from the environment in the whole computer system.
Use
Through the virtual machine software, you can in a physical computer simulate one or more virtual computer, these virtual machine like a real computer work, for example you can install the operating system, install applications, access cyber source etc.. For you, it only runs in your physical computer with a single application, but for running in the virtual machine applications, it is a real computer. Therefore, when I was in the virtual machine for software testing, may system will collapse, however, collapse only on Java virtual machine operating system, rather than on the physical computer operating system, and the use of the virtual machine, the" Undo" ( recovery ) function, I can immediately restore the virtual machine to install the software before state.
Virtual system and the virtual machine is different
Virtual system actually by Prayaya fast V3 virtual system for representing the existing operating system, by generating a new virtual mirror image, it has a real windows system exactly the same function, enter the virtual system, all operations are in this new independent virtual system inside, can be independently mounted operation software, data storage, with own desktop, the system will not have any real impact, but also in the existing system and the virtual mirror flexible switching between a kind of operating system. Virtual system and traditional virtual machine ( Vmware, VirtualBox, Virtual PC ), virtual system does not degrade computer performance, virtual system does not need to start the windows system such as time consuming, run the program more convenient.
Fast image V3 virtual system technical index
Below is the technical parameters: CPU occupancy: no more than 5%; the memory footprint: not more than 30M; disk usage: not more than 20M; whether the support network: support; whether to support the network sharing: support; whether to support the software native installation: support; system support platform compatibility: compatible with Windows XP, Windows 7; mobility platform system: support.
Virtual machine
The popular virtual machine software VMware ( VMWare ACE ), Virtual Box and Virtual PC, they can be in the Windows system on a number of virtual computer.
