10 # Script for configuring a vif in routed mode.
11 # The hotplugging system will call this script if it is specified either in
12 # the device configuration given to Xend, or the default Xend configuration
13 # in /etc/xen/xend-config.sxp. If the script is specified in neither of those
14 # places, then vif-bridge is the default.
17 # vif-route (add|remove|online|offline)
20 # vif vif interface name (required).
21 # XENBUS_PATH path to this device's details in the XenStore (required).
22 # Read from the store:
23 # ip list of IP networks for the vif, space-separated (default given in
25 # V6PREFIX prefix of v6 address to use
26 # Note that the v6 support is kind of broken because there's not really a way to populate the v6 prefix
27 # This script will set up proxy arp for any ip addresses that are being routed
28 # type read to determine if the device is ioemu
