-#
-XENDOMAINS_SYSRQ=""
-
-## Type: integer 
-## Default: 100000
-#
-# If XENDOMAINS_SYSRQ is set, this variable determines how long to wait
-# (in microseconds) after each SysRq, so the domain has a chance to react.
-# If you want to a quick'n'dirty shutdown via SysRq, you may want to set
-# it to a relatively high value (1200000).
-#
-XENDOMAINS_USLEEP=100000
-
-## Type: integer
-## Default: 5000000
-#
-# When creating a guest domain, it is sensible to allow a little time for it
-# to get started before creating another domain or proceeding through the
-# boot process.  Without this, the booting guests will thrash the disk as they
-# start up.  This timeout (in microseconds) specifies the delay after guest
-# domain creation.
-#
-XENDOMAINS_CREATE_USLEEP=5000000
-
-## Type: string
-## Default: ""
-#
-# Set this to a non-empty string if you want to migrate virtual machines
-# on shutdown. The string will be passed to the xm migrate DOMID command
-# as is: It should contain the target IP address of the physical machine
-# to migrate to and optionally parameters like --live. Leave empty if
-# you don't want to try virtual machine relocation on shutdown.
-# If migration succeeds, neither SAVE nor SHUTDOWN will be executed for
-# that domain.
-#
-XENDOMAINS_MIGRATE=""
-
-## Type: string
-## Default: /var/lib/xen/save
-#
-# Directory to save running domains to when the system (dom0) is
-# shut down. Will also be used to restore domains from if # XENDOMAINS_RESTORE
-# is set (see below). Leave empty to disable domain saving on shutdown 
-# (e.g. because you rather shut domains down).
-# If domain saving does succeed, SHUTDOWN will not be executed.
-#
-XENDOMAINS_SAVE=/var/lib/xen/save
-
-## Type: string
-## Default: "--halt --wait"
-#
-# If neither MIGRATE nor SAVE were enabled or if they failed, you can
-# try to shut down a domain by sending it a shutdown request. To do this,
-# set this to "--halt --wait". Omit the "--wait" flag to avoid waiting
-# for the domain to be really down. Leave empty to skip domain shutdown.
-#

-
-## Type: string
-## Default: "--all --halt --wait"
-#
-# After we have gone over all virtual machines (resp. all automatically
-# started ones, see XENDOMAINS_AUTO_ONLY below) in a loop and sent SysRq,
-# migrated, saved and/or shutdown according to the settings above, we
-# might want to shutdown the virtual machines that are still running

-# Leave empty if you don't want to start domains automatically
-# (or just don't place any xen domain config files in that dir).
-# Note that the script tries to be clever if both RESTORE and AUTO are 
-# set: It will first restore saved domains and then only start domains
-# in AUTO which are not running yet. 
-# Note that the name matching is somewhat fuzzy.
-#
-XENDOMAINS_AUTO=/etc/xen/auto
-
-## Type: boolean
-## Default: false
-# 
-# If this variable is set to "true", only the domains started via config 
-# files in XENDOMAINS_AUTO will be treated according to XENDOMAINS_SYSRQ,
-# XENDOMAINS_MIGRATE, XENDOMAINS_SAVE, XENDMAINS_SHUTDOWN; otherwise
-# all running domains will be. 
-# Note that the name matching is somewhat fuzzy.
-# 
-XENDOMAINS_AUTO_ONLY=false
-
-## Type: integer
-## Default: 300
-#
-# On xendomains stop, a number of xm commands (xm migrate, save, shutdown,
-# shutdown --all) may be executed. In the worst case, these commands may
-# stall forever, which will prevent a successful shutdown of the machine.
-# If this variable is non-zero, the script will set up a watchdog timer
-# for every of these xm commands and time it out after the number of seconds
-# specified by this variable.
-# Note that SHUTDOWN_ALL will not be called if no virtual machines or only
-# zombies are still running, so you don't need to enable this timeout just
-# for the zombie case.
-# The setting should be large enough to make sure that migrate/save/shutdown
-# can succeed. If you do live migrations, keep in mind that live migration
-# of a 1GB machine over Gigabit ethernet may actually take something like
-# 100s (assuming that live migration uses 10% of the network # bandwidth).
-# Depending on the virtual machine, a shutdown may also require a significant
-# amount of time. So better setup this variable to a huge number and hope the
-# watchdog never fires.

-#============================================================================
-# Default Xen network start/stop script.
-# Xend calls a network script when it starts.
-# The script name to use is defined in /etc/xen/xend-config.sxp
-# in the network-script field.
-#
-# This script creates a bridge (default ${netdev}), adds a device
-# (defaults to the device on the default gateway route) to it, copies
-# the IP addresses from the device to the bridge and adjusts the routes
-# accordingly.
-#
-# If all goes well, this should ensure that networking stays up.
-# However, some configurations are upset by this, especially
-# NFS roots. If the bridged setup does not meet your needs,
-# configure a different script, for example using routing instead.
-#
-# Usage:
-#
-# network-bridge (start|stop|status) {VAR=VAL}*
-#
-# Vars:
-#
-# bridge     The bridge to use (default ${netdev}).
-# netdev     The interface to add to the bridge (default gateway device).
-# antispoof  Whether to use iptables to prevent spoofing (default no).
-#
-# Internal Vars:
-# pdev="p${netdev}"
-# tdev=tmpbridge
-#
-# start:
-# Creates the bridge as tdev
-# Copies the IP and MAC addresses from pdev to bridge
-# Renames netdev to be pdev 
-# Renames tdev to bridge
-# Enslaves pdev to bridge
-#
-# stop:
-# Removes pdev from the bridge
-# Transfers addresses, routes from bridge to pdev
-# Renames bridge to tdev
-# Renames pdev to netdev 
-# Deletes tdev
