What is QEMU/KVM?

In essence, QEMU/KVM are used to achieve virtual machines (VM) on Linux with high performanace through GPU acceleration. It offers more customibility and performance comparing with other existing VM softwares such as GNOME Boxes and VMware.

QEMU stands for Quick Emulator, it's the main virtualisation software that allows full-system emulation. KVM stands for Kernel-based Virtual Machine, it's a Linux kernel module that allows VM to run efficiently at kernel level.
