虚拟机能使电脑一台顶n台（The virtual function enables a computer to top a n platform） Little knowledge: what is a virtual machine? A virtual machine is an application that runs on a Windows or Linux computer, and the application simulated a X86 based standard PC environment. The environment and ordinary computers, have chipset, CPU, memory, video card, sound card, network card, hard disk, floppy drive, CD-ROM, serial and parallel ports, USB controller, SCSI controller and other equipment, to provide the application of the window is the virtual machine monitor. In use, the virtual machine and the host really is not much difference, need to partition, format, install the operating system, install the application software and, in short, like a real computer. Easy simulation of multiple system environments For the crowd: program developers, programming enthusiasts Features: multi system simulation, avoid system confusion Previous developers have been able to just compile the program on their computer. For developers, considering the diversity of existing operating systems and environments, the programs they develop need to be tested in a variety of situations. In this way, we can use VMware Workstation (or Microsoft Virtual PC) to test by installing virtual machines with different operating systems and environments. If you are doing some development based on Windows or Linux, you can install multiple virtual machines and install different operating systems in each virtual machine for testing. Using VMware Workstation 5.5 and its later version, you can use its snapshot capabilities to configure different environments in the same virtual machine. For example, we created a Windows XP virtual machine that we can do when the installation is complete. Before you hit SP1 and create a snapshot before you hit the SP2 patch, you can quickly revert to the snapshot state when using these snapshots. If you are doing some bottom development, youd better use the virtual machine provided by Micros
