No, that's wrong.

1) eth0=mcast like he did at the beginning is supposed to work, if it doesn't 
the host kernel is missing the "IP: multicast routing" option 
(CONFIG_IP_MROUTE) or "IP: multicasting" (CONFIG_IP_MULTICAST).

2) Your configuration is invalid.
What you call "address" is multicast_address and must be a multicast one, like 
239.192.168.1 (the default one, valid for local use).

See 
http://user-mode-linux.sourceforge.net/networking.html
and (reachable from there):
http://user-mode-linux.sourceforge.net/text/mcast.txt

That's because Debian already ran that command, so it already created the 
communication socket. You don't need to run your own daemon.

To use that socket, you need to use eth0=daemon, but it will look 
for /tmp/uml.ctl, so you must specify the path:

eth0=daemon,,,/var/run/uml-utilities/uml_switch.ctl

and it'll work like your eth0=daemon setup.
