Hi,

after opening the remote console to the VM and doing a "ps aux" on the host you'll see something like this:

root 12022 0.4 0.0 63860 3016 ? Ss 17:18 0:00 sshd: r...@notty root 12027 0.0 0.0 11436 780 ? Ss 17:18 0:00 nc 127.0.0.1 5900

Now, when after closing the console window virt-manager freezes, kill the nc process manually and all will be well again.

I think this is the relevant part in virt-manager's source (details.py):

    def close_tunnel(self):
        if self.vncTunnel is None:
            return

logging.debug("Shutting down tunnel PID %d FD %d" % (self.vncTunnel[1], self.vncTunnel[0].fileno()))
        self.vncTunnel[0].close()
        os.waitpid(self.vncTunnel[1], 0)
        self.vncTunnel = None

I'm not a coder myself so I don't know how to fix this. I just hope this might help someone.
