# Xend configuration file.

#

# This example configuration is appropriate for an installation that 

# utilizes a bridged network configuration. Access to xend via http

# is disabled.

# specified.

# The Xen-API server configuration.

#

# This value configures the ports, interfaces, and access controls for the

# Xen-API server.  Each entry in the list starts with either unix, a port

# number, or an address:port pair.  If this is "unix", then a UDP socket is

# opened, and this entry applies to that.  If it is a port, then Xend will

# listen on all interfaces on that TCP port, and if it is an address:port

# pair, then Xend will listen on the specified port, using the interface with

# the specified address.

#

# The subsequent string configures the user-based access control for the

# listener in question.  This can be one of "none" or "pam", indicating either

# that users should be allowed access unconditionally, or that the local

# Pluggable Authentication Modules configuration should be used.  If this

# string is missing or empty, then "pam" is used.

#

# The final string gives the host-based access control for that listener. If

# this is missing or empty, then all connections are accepted.  Otherwise,

# this should be a space-separated sequence of regular expressions; any host

# with a fully-qualified domain name or an IP address that matches one of

# these regular expressions will be accepted.

#

# Example: listen on TCP port 9363 on all interfaces, accepting connections

# only from machines in example.com or localhost, and allow access through

# the unix domain socket unconditionally:

#

#   (xen-api-server ((9363 pam '^localhost$ example\\.com$')

# dom0: ----------------- bridge -> real eth0 -> the network

#                            |

# domU: fake eth0 -> vifN.0 -+

__CLUSTER_BRIDGE_CLAUSE__

# Your default ethernet device is used as the outgoing interface, by default. 

# To use a different one (e.g. eth1) use

#

# (network-script 'network-bridge netdev=eth1')

#

# The bridge is named xenbr0, by default.  To rename the bridge, use

#

# (network-script 'network-bridge bridge=<name>')

#

# It is possible to use the network-bridge script in more complicated

# scenarios, such as having two outgoing interfaces, with two bridges, and

# two fake interfaces per guest domain.  To do things like this, write

# yourself a wrapper script, and call network-bridge from it, as appropriate.

#

# The script used to control virtual interfaces.  This can be overridden on a

# per-vif basis when creating a domain or a configuring a new vif.  The

# vif-bridge script is designed for use with the network-bridge script, or

# similar configurations.

#

# If you have overridden the bridge name using

# (network-script 'network-bridge bridge=<name>') then you may wish to do the

# same here.  The bridge name can also be set when creating a domain or

# configuring a new vif, but a value specified here would act as a default.

#

# If you are using only one bridge, the vif-bridge script will discover that,

# so there is no need to specify it explicitly.

# File Format

# -----------

#

#  Anything following a '#' character is ignored as a comment.

#

#  Otherwise the format of this file "key = value".  The value of

# any keys in this file may be constructed via the output of a command.

#

#  For example:

#

#         kernel = /boot/vmlinuz-`uname -r`

#

##

#

##

#  Output directory for storing loopback images.

#

#  If you choose to use loopback images, which are simple to manage but

# slower than LVM partitions, then specify a directory here and uncomment

# the line.

#

#  New instances will be stored in subdirectories named after their

# hostnames.

#

#

#  Installation method.

#

#  There are four distinct methods which you may to install a new copy

# of Linux to use in your Xen guest domain:

#

#   - Installation via the debootstrap command.

#   - Installation via the rpmstrap command.

#   - Installation via the rinse command.

#   - Installation by copying a directory containing a previous installation.

#   - Installation by untarring a previously archived image.

#

#  NOTE That if you use the "untar", or "copy" options you should ensure

# that the image you're left with matches the 'dist' setting later in

# this file.

#

#

##

#

# 

# install-method = [ debootstrap | rinse | rpmstrap | copy | tar ]

#

#

install-method = debootstrap

#

# If you're using the "copy", or "tar" installation methods you must

# need to specify the source location to copy from, or the source

# .tar file to unpack.

#

# You may specify that with a line such as:

#

# install-source = /path/to/copy

# install-source = /some/path/img.tar

#

#

#

##

#  Command definitions.

##

#

# The "rinse", and "rpmstrap" commands are hardwired into 

# the script, but if you wish to modify the commands which are executed

# when installing new systems by a "copy", "debootstrap", or "tar" method

# you can do so here:

#

# (This allows you to install from a .tar.bz file, rather than a plain

# tar file, use cdebootstrap, etc.)

#

# install-method = copy:

# copy-cmd = /bin/cp -a $src/* $dest

#

# install-method = debootstrap:

# debootstrap-cmd = /usr/sbin/debootstrap
