Software recommendation: free to travel to create a portable virtual machine

When we want to run a program on another system in one operating system, we usually need to install a virtual machine to do so because the system kernel is different. However, the installation of a regular virtual machine is rather troublesome, and we may not be allowed to install software when we switch to another computer, so we can create a portable virtual machine to solve this problem. Here is an example of how to create a green portable VirtualBox virtual machine.

First, go to下载Portable-VirtualBox and then download the corresponding version of VirtualBox from the VirtualBox homepage (note that both software version numbers should be the same). After launching Portable-VirtualBox, click “search” and select the above downloaded “VirtualBox” installation file, and check the 32 and 64 bit versions (Figure 1).

Click OK and the program will start to complete the creation of the green version of “VirtualBox”. The created green version is saved by default in the APP directory under the “Portable-VirtualBox” installation directory, such as C:UsersAdministratorDesktopPortable-VirtualBoxapp64 ” (Figure 2).

Now you can copy all of the above directories to a flash drive, insert the flash drive into any computer with Windows installed, and run “VirtualBox.EXE” to start the virtual machine. After starting the virtual machine, click “Setting” to enter the settings and turn on the USB settings so that the portable virtual machine can directly read the contents of the USB device such as the virtual machine system files, configuration, etc. (Figure 3).

After completing the above settings, you can create a new virtual machine, in order to facilitate the reading of virtual machine files, in the new virtual machine hard disk settings to select “Use an existing virtual disk file” (using the existing virtual file), so that the commonly used virtual system files are first set to save in the In order to read the files of the virtual machine, you should select “Use an existing virtual disk file” in the new virtual machine hard disk settings.
