virtual operating system you need to install the appropriate driver.Finally, the virtual machine runs as follows:As you can see, the program provides an interface with a very rich menu of features that are very powerful and can even send combination keys to the operating system in the virtual machine.So to speak, if there is no VirtualBox, the QEMU+KVM combination should be the preferred choice for desktop users. Next I will try Virtualbox,virtualbox
