I'm not familiar with noVNC, but from very little I read, it uses
websockets. Libvirt has support for that since 1.0.6:


Also, qemu already has VNC server built in - that's why it already
serves VNC data on ports 5900+ (or whatever you configure). So I'm not
sure that you want another VNC server to connect to it (or novnc_server
is not VNC server and I am just blabbing about nothing?).
