Hi Guido,

I am using squeeze with dependency based booting.

So I modified the libvirt-bin in init.d:
  start)
        if check_start_libvirtd_option; then
                log_daemon_msg "Starting $DESC" "$NAME"
                if running ;  then
                        log_progress_msg "already running"
                        log_end_msg 0
                        exit 0
                fi
                rm -f /var/run/libvirtd.pid
                /sbin/ifconfig > /root/if-boot
                start-stop-daemon --start --quiet --pidfile $PIDFILE \
                        --exec $DAEMON -- $libvirtd_opts
                if running; then
                        log_end_msg 0
                else
                        log_end_msg 1
                fi
        fi
        ;;


After a reboot I checked /root/if-boot.
All the tap devices were created successfully, but still I got the
following error:

Sep 27 10:21:22 cloud libvirtd: 10:21:22.407: error :

What I also see in the libvirt logs:

On reboot it starts with:

When I manually do /etc/init.d/libvirt-bin restart it does: (see the
HOME=/root USER=root LOGNAME=root). But that should make any difference?

Thanks for the follow up!
