<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>
