{{Admon/note|About KVM|There are actually several key programs installed for virtualization using KVM:<ul><li>'''kvm/qemu''' - the hypervisor and other hardware emulation systems.</li><li>A system service named '''libvirtdlibvirt''' that manages the VMs.</li><li>A graphical tool for managing virtual machines ('''virt-manager''') and the '''virsh''' command-line tool.</li></ul>}}
|}
</li><li>Start the virtualization service: <b><code><span style="color:#3366CC;font-size:1.2em;">sudo systemctl start libvirtdlibvirt</span></code></b><br><br>'''NOTE:''' The most recent variants of CentOS and Fedora are using a service called '''firewalld''' that replaces '''iptables''', however the ''iptables'' service is still in relatively common usage and knowing how to use it also works with firewalld. In this course we will concentrate on ''iptables''.<br><br></li>
<li>To disable and remove firewalld, issue the following commands:<br>
<b><code><span style="color:#3366CC;font-size:1.2em;">sudo systemctl disable firewalld</span></code></b><br>
