 SPICE 控制台

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.

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 nova-spicehtml5proxy service by using SPICE-over-websockets. The nova-spicehtml5proxy service communicates directly with the hypervisor process by using SPICE.

VNC must be explicitly disabled to get access to the SPICE console. Set the vnc_enabled option to False in the [DEFAULT] section to disable the VNC console.

Use the following options to configure SPICE as the console for OpenStack Compute:
