+.VNC clipboard
+You can enable the VNC clipboard by setting `clipboard` to `vnc`.
+
+----
+# qm set <vmid> -vga <displaytype>,clipboard=vnc
+----
+
+In order to use the clipboard feature, you must first install the
+SPICE guest tools. On Debian-based distributions, this can be achieved
+by installing `spice-vdagent`. For other Operating Systems search for it
+in the offical repositories or see: https://www.spice-space.org/download.html
+
+Once you have installed the spice guest tools, you can use the VNC clipboard
+function (e.g. in the noVNC console panel). However, if you're using
+SPICE, virtio or virgl, you'll need to choose which clipboard to use.
+This is because the default *SPICE* clipboard will be replaced by the
+*VNC* clipboard, if `clipboard` is set to `vnc`.
