<title>Spice Console</title>
<para>OpenStack Compute has long had support for VNC consoles to
guests. The VNC protocol is fairly limited, lacking support for
multiple monitors, bi-directional audio, reliable cut+paste, video
streaming and more. SPICE is a new protocol which aims to address
all the limitations in VNC, to provide good remote desktop
support.</para>
<para>SPICE support in OpenStack Compute shares a similar
architecture to the VNC implementation. The OpenStack Dashboard
uses a SPICE-HTML5 widget in its console tab, that communicates to
the <literal>nova-spicehtml5proxy</literal> service using
SPICE-over-websockets. The <literal>nova-spicehtml5proxy</literal>
service communicates directly with the hypervisor process using SPICE.<note>
<para>If Spice is not configured correctly, Compute will fall
back upon VNC.</para>

<para>Options for configuring SPICE as the console for OpenStack Compute can be found below.</para>
