[Xen-devel] Re: No shutdown of domU: xenbus_dev_shutdown: device/console
Hmm .. i haven't received any response, is there anyone who could point me to
the functions involved in communicating the state of the console from
"initializing" to "connected" ?
That way i could at some additional printk's to find out why the state of domU
consoles stays "1" instead of "4" in xenstore.
