I can't exacly figure out what you mean.
Here is my vif-bridge:


# Enslaves the vif interface to the bridge and adds iptables rules
# for its ip addresses (if any).
#
# down:
# Removes the vif interface from the bridge and removes the iptables
# rules for its ip addresses (if any).
#===========================================================================

set -x

dir=$(dirname "$0")
. "$dir/vif-common.sh"

bridge=${bridge:-}
bridge=$(xenstore_read_default "$XENBUS_PATH/bridge" "$bridge")

if [ -z "$bridge" ]
then
  bridge=$(brctl show | cut -d "
" -f 2 | cut -f 1)

  if [ -z "$bridge" ]
  then
     fatal "Could not find bridge, and none was specified"
  fi
fi

case "$command" in
    online)
        if brctl show | grep "$vif" >&/dev/null
        then
          log debug "$vif already attached to a bridge"
          exit 0
        fi

        brctl addif "$bridge" "$vif" ||
          fatal "brctl addif $bridge $vif failed"

        ifconfig "$vif" up || fatal "ifconfig $vif up failed"
        ;;

        # vifs are auto-removed from bridge.

Is set -x in correct position?


And my udev.conf looks now like this.

[root@ingpcxen002 log]# vi /etc/udev/udev.conf
# udev.conf
# The main config file for udev
#
# This file can be used to override some of udev's default values
# for where it looks for files, and where it places device nodes.
#
# WARNING: changing any value, can cause serious system breakage!
#

# udev_root - where in the filesystem to place the device nodes
udev_root="/dev/"

# udev_db - The name and location of the udev database.
udev_db="/dev/.udev.tdb"

# udev_rules - The name and location of the udev rules file
udev_rules="/etc/udev/rules.d/"

# udev_permissions - The name and location of the udev permission file
udev_permissions="/etc/udev/permissions.d/"

#udev log
#udevcontrol
log_priority="debug"

# default_mode - set the default mode for all nodes that have no
#                explicit match in the permissions file
default_mode="0600"

# default_owner - set the default owner for all nodes that have no
#                 explicit match in the permissions file
default_owner="root"

# default_group - set the default group for all nodes that have no
#                 explicit match in the permissions file
default_group="root"

# udev_log - set to "yes" if you want logging, else "no"
udev_log="yes"







Is this also correct?????

Are you using bridged network?

Could you add "set -x" to begining of
/etc/xen/scripts/vif-{bridge,route,nat} and set log_priority on udev
to debug? ("udevcontrol log_priority=debug" does that in runtime, or
you can set that on udev.conf and restart udevd)

After that you will have on /var/log/debug a very usefull log of
hotplug script responsible for setting up vif.
