the remove event, the script environment variable has disappeared, so we must hook on the offline event instead. This fix was put into xen-backend.rules, but not the vif scripts, so they were out of sync, and the interfaces were not being properly closed down. Signed-off-by: Ewan Mellor <ewan@xensource.com>

# Script for configuring a vif in routed-nat mode.
|
|
# The hotplugging system will call this script if it is specified either in
|
|
# the device configuration given to Xend, or the default Xend configuration
|
|
# in /etc/xen/xend-config.sxp. If the script is specified in neither of those
|
|
# places, then vif-bridge is the default.

# Usage:
|
|
# vif-nat (add|remove|online|offline)
|
|
#
|
|
# Environment vars:
|
|
# vif vif interface name (required).
|
|
# XENBUS_PATH path to this device's details in the XenStore (required).
|
|
#
|
|
# Read from the store:
|
|
# ip list of IP networks for the vif, space-separated (default given in

# this script).
