The major advantage of QEMU is that it is very easy to set up and manage. Users often use QEMU alongside KVM as it provides a natively implemented virtual machine on the Linux kernel. QEMU is a virtual machine emulator and virtualizer which is quite similar to VMware and VirtualBox on Windows. With that, you will be able to use native macOS software that is not otherwise available in Linux. This guide will show you how to install macOS on Ubuntu Linux using a QEMU-KVM Virtual Machine. Besides, you can rest assured that if something goes wrong with the virtual machine, it won't break your existing host operating system. They primarily allow us to test and use different operating systems without the need for extra hardware.
Virtual machines are very important in computing and software engineering.
