Terminology
*virt-manager* is based on a set of lower level virtualization tools,
going from the user interface to the hardware interactions with the
processor. This terminology is a bit confusing and other documentation
might mention the following tools:
*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.
*virt-manager* is the graphical interface that allows to create, configure, and run virtual machines.
