A virtual machine is a software that can be used to simulate the installation environment of a real computer and use them just like a computer. When we want to test whether a software is safe or not, and we are afraid that using the software on the host computer is toxic, then we need to use a virtual machine. A virtual machine has exactly the same functions as a real windows system. After entering the virtual system, all operations are performed inside this new independent virtual system, which can install and run software independently, save data, and have its own independent desktop without any impact on the real system. The following are a few commonly used virtual machine software, let’s learn more about it.
1. VirtualBox
VirtualBox is a free and open source virtual machine software developed by Innotek, Germany and launched by Sun Microsystems, which is very widely used. Users can install and execute Solaris, Windows, DOS, Linux, OS/2 Warp, BSD and other systems as client operating systems on VirtualBox.
VirtualBox is completely free and open source and can run cross-platform on Win, Mac, and Linux systems. With the powerful and excellent performance of this virtual machine, it can smoothly run all major mainstream operating systems, such as the full range of Microsoft (including Windows 10) / Linux distributions (Ubuntu/CentOS/Deepin) and even Android, and can cope with the needs of various scenarios.
2.VMware Player
VMware Player is an application that allows PC users to easily run virtual machines on Windows or Linux PCs. It can’t be used to create virtual systems. However, the latest version 6.0 is now able to create virtual systems. For example, the official website of VMware provides a large number of system virtual machine files, as well as various virtual machine application environments, which users can download and run directly in VMware Player.
3. vmware workstation
VMware Workstation is a powerful computer desktop virtualization software that provides users with the best solution for developing, testing, and deploying new applications while running different operating systems on a single desktop.
VMware Workstation simulates a complete network environment on a physical machine and a portable virtual machine, providing greater flexibility and advanced technology than any other virtual computing software on the market.
For enterprise IT developers and system administrators, VMware’s features of virtual networking, live snapshots, drag-and-drop shared folders, PXE support and more make it an essential tool.
4.Microsoft Virtual PC
Microsoft Virtual PC is a free virtual machine software from Microsoft that allows you to run multiple operating systems on a single PC at the same time. With it, you don’t need to reboot the system, just click the mouse to open a new operating system or switch between operating systems. From now on, you can use one machine as many, without infringing on each other.
Installing VPC software does not require any repartitioning or identification of the hard disk, and you can run multiple operating systems that you have already installed very smoothly. And also the ability to share files and applications between several virtual PCs using drag-and-drop functionality can provide a secure environment for you to run legacy applications to maintain compatibility, it can save reconfiguration time, making your support, development, training efforts can be more effective.
5.java virtual machine
Java Virtual Machine (JVM) is the abbreviation of Java Virtual Machine, which is a fictional computer that is implemented by simulating various computer functions simulated on the actual computer. java virtual machine has its own perfect hardware architecture, such as processor, stack, registers, etc., and also has the corresponding instruction system.
The Java virtual machine shields the information related to the specific operating system platform, so that the Java language compiled program only needs to generate the target code (byte code) that runs on the Java virtual machine, and can run on a variety of platforms without modification. when the Java virtual machine executes the byte code, it actually ends up interpreting the byte code into machine instructions for execution on the specific platform.
