Hello to everyone.
Is it possible to implement noVNC tunneling through SSH?
Before noVNC connection is established local port is forwarded to remote machine like this:

ssh -L 15900:127.0.0.1:5900 remote.host.net

Then noVNC simply connects to localhost:15900 where WebVirtMgr is installed.
It will be great as we get several advantages:

Single open port.
Connection encryption.
Strong authentification type with SSH keys on managed host.

Extremly useful when you have several dedicated servers on different data-centers and don't want to build distributed networks using VPN/MPLS/Else.

Several futher thoughts.
The best way to reach a goal is to use paramiko before launching noVNC.
Something like this:

import paramiko
import sys
from forward import forward_tunnel

remote_host = "localhost"
remote_port = 59XX
local_port  = 118XX
ssh_host    = "host_with_qemukvm_installed"
ssh_port    = 22

user     = "webvirtmgr"
password = "supersecret"

transport = paramiko.Transport((ssh_host, ssh_port))

# Command for paramiko-1.7.7.1
transport.connect(hostkey  = None,
                  username = user,
                  password = password,
                  pkey     = None)

try:
    forward_tunnel(local_port, remote_host, remote_port, transport)
except KeyboardInterrupt:
    print 'Port forwarding stopped.'
    sys.exit(0)
