<title>SPICE console</title>
|
|
<para>OpenStack Compute supports VNC consoles to guests. The VNC
|
|
protocol is fairly limited, lacking support for multiple monitors,
|
|
bi-directional audio, reliable cut-and-paste, video streaming and
|
|
more. SPICE is a new protocol that aims to address the limitations
|
|
in VNC and 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 <systemitem class="service">nova-spicehtml5proxy</systemitem>
|
|
service by using SPICE-over-websockets. The <systemitem
|
|
class="service">nova-spicehtml5proxy</systemitem> service
|
|
communicates directly with the hypervisor process by using SPICE.<note>
|
|
<para>If you do not configure SPICE correctly, Compute falls
|
|
back on VNC.</para>

<para>The following table shows the options to configure SPICE as
|
|
the console for OpenStack Compute:</para>
