Tools: hv: Add an example script to configure an interface

#!/bin/bash

# This example script activates an interface based on the specified

# configuration.

#

# In the interest of keeping the KVP daemon code free of distro specific

# information; the kvp daemon code invokes this external script to configure

# the interface.

#

# The only argument to this script is the configuration file that is to

# be used to configure the interface.

#

# Each Distro is expected to implement this script in a distro specific

# fashion. For instance on Distros that ship with Network Manager enabled,

# this script can be based on the Network Manager APIs for configuring the

# interface.

#

# This example script is based on a RHEL environment.

#

# Here is the format of the ip configuration file:

#

# HWADDR=macaddr

# IF_NAME=interface name

# DHCP=yes (This is optional; if yes, DHCP is configured)

#

# IPADDR=ipaddr1

# IPADDR_1=ipaddr2

# IPADDR_x=ipaddry (where y = x + 1)

#

# NETMASK=netmask1

# NETMASK_x=netmasky (where y = x + 1)

#

# GATEWAY=ipaddr1

# GATEWAY_x=ipaddry (where y = x + 1)

#

# DNSx=ipaddrx (where first DNS address is tagged as DNS1 etc)

#

# IPV6 addresses will be tagged as IPV6ADDR, IPV6 gateway will be

# tagged as IPV6_DEFAULTGW and IPV6 NETMASK will be tagged as

# IPV6NETMASK.

#

# The host can specify multiple ipv4 and ipv6 addresses to be

# configured for the interface. Furthermore, the configuration

# needs to be persistent. A subsequent GET call on the interface

# is expected to return the configuration that is set via the SET

# call.

#

echo "IPV6INIT=yes" >> $1

echo "NM_CONTROLLED=no" >> $1

echo "PEERDNS=yes" >> $1

echo "ONBOOT=yes" >> $1

then
