 It means you didn't install libvirt in the node. Fix it this way:
 
+For Ubuntu 18.04:
 
 .. code-block:: bash
 
-    root@node:~# apt get install libvirt-bin
+    root@node:~# apt-get install libvirt-bin
+    
+From Ubuntu 18.10 instead of libvirt-bin you need install libvirt-daemon-system and libvirt-clients.
+
+.. code-block:: bash
+
+    root@node:~# apt-get install libvirt-daemon-system
+    root@node:~# apt-get install libvirt-clients
