It has an easy and intuitive UI, supports all the features I needed and is open-source. But this time I decided to use another widely recognized virtualization solution on Linux, qemu, along with kvm.</p> <p>First of all, let me give some brief idea about qemu, virt-manager and kvm. Qemu is the software which can be used to install and run a guest OS on top of the actual OS to put it in a very simple way although it's much more powerful than that. It can be compared to Virtualbox except that qemu itself does not have a UI, instead it's a command line utility. Virt-manager is some thing that provides a GUI to qemu. Together virt-manager and qemu can be thought of as the Virtualbox. On the other hand, kvm is the Linux kernel module that can help qemu execute the virtualized instructions directly on the CPU which can improve the performance greatly. This is to be kept in mind that qemu can run even without kvm but the speed will be much slower.</p>
