In linux Kvm/qemu is generally used for virtuulization but libvirt supports Xen, Virtualbox, Vmware, Hyperv too.I not gonna dive to deep. So start using it.
To install and see info about the libvirt packet. As you see it is very little tiny packet and it install a daemon to control virtualization.

As you can see daemon is active.
$ sudo systemctl status libvirtd
libvirtd.service - Virtualization daemon
