This is bad - you can't have a while loop which sits for 5 seconds in an
even handler in GTK because it will block all UI events from running.

The console code already has support for auto-connecting to the console
with retries. When popping up the console it will retry after 125 ms,
250ms, 500ms, 1s, 2s and then every 2s upto 10 times. 

I'm interested to know what this isn't working for you ?  Check the log
file /root/.virt-manager/virt-manager.log which should show you messages
every time it tries to open the console. The code for re-trying the console
connection is in src/virtManager/console.py in the try_login() method.
