Xen users - May 2008 - 2.6.25: xm console doesn''t work: "XENBUS: Device with no driver: device/console/0"

Previously, I used to run 2.6.18 kernel built from Xen sources.

I just tried to run a 2.6.25.1 domU kernel on top of Xen 3.2 - after 
changing domU''s config file here and there, I successfully booted the 
guest, but I''m still unable to use xm console.

When I start the domain, it displays all kernel and bootup messages, but 
I don''t get any prompt after the bootup is done.

I noticed this message in dmesg, which seem (?) to indicate the cause:

   XENBUS: Device with no driver: device/console/0

But I have the Xen console driver built-in:

# grep -i xen .config
CONFIG_XEN=y
CONFIG_XEN_BLKDEV_FRONTEND=y
CONFIG_XEN_NETDEV_FRONTEND=y
CONFIG_HVC_XEN=y


Or is the problem somewhere else, in /etc/inittab perhaps?

Replying to myself.

Looks like:

1:2345:respawn:/sbin/mingetty hvc0

did the trick.

Still, why does XENBUS complain about "Device with no driver: 
device/console/0"?
