Template: nova-consoleproxy/daemon_type Type: select Choices: spicehtml5, xenvnc, novnc Default: spicehtml5 _Description: Type of console daemon to start at boot time: Nova Console supports 3 types of consoles. One is specific to Xen, called XVP (Xen VNC Proxy), and the other daemon supports KVM. While the SPICE protocol is normally faster than VNC, it also requires support for web sockets in your browser, and that is a feature only very modern browsers have support for. . This can later be edited in /etc/default/nova-consoleproxy.
