Virtual Machine on Fedora
Be sure to have installed libvirt - yum install @virtualization should get the most necessary item installed.
Next ensure that the virtualisation is started
]# systemctl start libvirtd
If needed enable the libvirtd if you want it to be started at every boot
]# systenctl enable libvirtd.service
When installing a new virtual machine do ensure that it runs on the kvm virtualisation, not the qemu - qemu is an emulator and run very slow.
