5 # Script for configuring a vif in bridged mode.
6 # The hotplugging system will call this script if it is specified either in
7 # the device configuration given to Xend, or the default Xend configuration
8 # in /etc/xen/xend-config.sxp. If the script is specified in neither of those
9 # places, then this script is the default.
10 #
11 # Usage:
12 # vif-bridge (add|remove|online|offline)
13 #
14 # Environment vars:
15 # vif vif interface name (required).
16 # XENBUS_PATH path to this device's details in the XenStore (required).
17 #
18 # Read from the store:
19 # bridge bridge to add the vif to (optional). Defaults to searching for the
20 # bridge itself.
21 # ip list of IP networks for the vif, space-separated (optional).
22 #
23 # up:
24 # Enslaves the vif interface to the bridge and adds iptables rules
25 # for its ip addresses (if any).
26 #
27 # down:
28 # Removes the vif interface from the bridge and removes the iptables
29 # rules for its ip addresses (if any).
