hotplug ones. Added evalVariables and findCommand functions to that, which we use to clarify the handling of variables being passed in as command line variables. Make vif-bridge able to find the bridge for itself if only one bridge is in use. This means that it is not necessary to specify a bridge in many configurations. Allow the bridge to be specified on the command line, meaning that a default may be provided in the xend-config.sxp if desired. Added xenstore_read_default to xen-hotplug-common.sh, which reads from the store but uses a given default if the path in the store is not present. This is used by vif-bridge to allow the store details (i.e. those given to xm create) to override the default value given in the xend-config.sxp. Remove vif-bridge setting -- the value can be specified on the vif-script command line if necessary. Added examples for network-nat/vif-nat. Added lots of big comments.

# To bridge network traffic, like this:

# bridge -> real eth0 -> the network
|

|
|
#
|
|
# use
|
|
#
|
|
# (network-script network-bridge)
|
|
#
|
|
# Your eth0 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.

# 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.
