Configuration Opennebula3.8 & 4.x Virtual Machines Contextualizing

   之前有个朋友告诉我，初始化配置脚本在windows下无法正确执行，当时我没有给与他明确的答复，后来经过测试发现了不同，如下所示：

Nebula3.8的Context.sh文件：

# Context variables generated by OpenNebula
DISK_ID= "1"
DNS_A= "202.106.0.20"
DNS_B= "202.96.69.38"
DRIVER= "file:"
GATEWAY= "192.168.10.1"
HOSTNAME= "centos6.3"
IP= "192.168.10.60"
NETMASK= "255.255.255.0"
TARGET= "hdb"

Nebula4.x的Context.sh文件：

# Context variables generated by OpenNebula
DISK_ID= '1'
ETH0_DNS= '202.106.0.20'
ETH0_GATEWAY= '192.168.10.1'
ETH0_IP= '192.168.10.2'
ETH0_MASK= '255.255.255.0'
ETH0_NETWORK= '192.168.10.0'
NETWORK= 'YES'
TARGET= 'vdb'

   在此，原nebula3.8的初始化脚本可继续使用，后面添加了nebula4.x下的初始化脚本。    细心的朋友会发现，nebula3.8的变量使用“双引号”，而nebula4.x版本的变量使用“单引号”，在原3.8的windows初始化脚本中有去除双引号的步骤，但是无法去除单引号，而windows系统认为set 变量“=”号后面的值都为变量值，如去除双引号后：set ETH0_IP='192.168.10.2'系统任务赋予ETH0_IP的值为'192.168.10.2'而非192.168.10.2，结果导致错误。另外变量定义也发生的改变，3.8中我以"IP"定义IP变量，而4.x中系统以"ETH0_IP"定义IP变量。

一、nebula3.8初始化脚本

1、Linux虚拟机：

(1).Linux虚拟机镜像配置：

[root@VM ~]# cd /tmp

[root@VM tmp]# vi contextualizing.sh

#!/bin/bash

for CDROM in $(ls /dev | grep "cdrom" | awk 'END{print}')

do

mount /dev/$CDROM /mnt

   if [ -f /mnt/CentOS_init.sh ]; then

       sh /mnt/CentOS_init.sh

   fi

       umount /mnt

done

# sed -i "/^sh/d"   /etc/rc.local

[root@VM tmp]# vi /etc/rc.local

加入一行：

sh /tmp/contextualizing.sh

********************************************************************************************

(2).Opennebula管理端配置init.sh脚本：

[oneuser@master ~]$ mkdir scripts

[oneuser@master ~]$ cd scripts

[oneuser@master scripts]$ vi CentOS_init.sh

#!/bin/bash

# By chensh at 2013/08/26

# This script for CentOS6

#Define...................

      HOSTS_NAME="/etc/hosts"

      NETWORK_HOSTS_NAME="/etc/sysconfig/network"

      INTERFACE="/etc/sysconfig/network-scripts/ifcfg-eth0"

      CFG_DNS="/etc/resolv.conf"

#Scripts start..............

if [ -f /mnt/context.sh ]; then

      . /mnt/context.sh

fi

if [ -n "$HOSTNAME" ]; then

      sed -i "/localhost/! d" $HOSTS_NAME

      echo "$IP $HOSTNAME" >> $HOSTS_NAME

      sed -i "/^HOSTNAME/d" $NETWORK_HOSTS_NAME

      echo "HOSTNAME=$HOSTNAME"  >> $NETWORK_HOSTS_NAME

fi

if [ -n "$IP" ]; then

      echo "DEVICE=eth0" > $INTERFACE

      echo "BOOTPROTO=static" >> $INTERFACE

      echo "ONBOOT=yes" >> $INTERFACE

      echo "IPADDR=$IP"  >> $INTERFACE

fi

if [ -n "$NETMASK" ]; then

      echo "NETMASK=$NETMASK" >> $INTERFACE

fi

if [ -n "$GATEWAY" ]; then

      echo "GATEWAY=$GATEWAY" >> $INTERFACE

      echo "TYPE=Ethernet" >> $INTERFACE

fi

if [ -n "$DNS_A" ]; then

      echo "nameserver  $DNS_A" > $CFG_DNS

fi

if [ -n "$DNS_B" ]; then

      sed -i "/nameserver/! d" $CFG_DNS

      echo "nameserver  $DNS_B" >> $CFG_DNS

fi

if [ -f /mnt/id_rsa.pub ]; then

      cat /mnt/id_rsa.pub > /root/.ssh/authorized_keys

fi

reboot

****************************************************************************************

(3).Opennebula Linux VM模版添加内容：

CONTEXT=[

 DNS_A="$NETWORK[DNS_A,NETWORK_ID=1]",

 DNS_B="$NETWORK[DNS_B,NETWORK_ID=1]",

 DRIVER="file:",

 FILES="/srv/cloud/one/scripts/CentOS_init.sh",

 GATEWAY="$NETWORK[GATEWAY,NETWORK_ID=1]",

 HOSTNAME="$NAME",

 IP="$NIC[IP]",

 NETMASK="$NETWORK[NETWORK_MASK,NETWORK_ID=1]",

 TARGET="hdb" ]

*NETWORK_ID为虚拟网络的ID号。

******************************************************************************

(4).Opennebula虚拟网络附加设置：

该附加设置便于虚拟机获取网关和DNS。

2、Windows虚拟机：

(1).Windows虚拟机镜像配置：

在C盘根目录下创建Windows_init.bat，内容如下：
