*KVM* is the module of the Linux kernel that interacts with the virtualization features of the processor.

*QEMU* is the virtualization software that emulates virtual processors and peripherals based on *KVM* and that starts and stops virtual machines.

*libvirt* is a library that allows *virt-manager* to interact with the virtualization capabilities provided by *QEMU*.

*SPICE* is a protocol that allows to visualize the desktop of virtual machines.
