XenServer自动化创建并初始化VM

转载自：http://heylinux.com/archives/2768.html

创建CentOS 6.9

环境介绍：

xenserver-test:192.168.0.37（一台XenServer主机）
centos-template:192.168.0.121（事先创建好的VM）
vm-host-1:192,168.0.122（将要创建的VM）

以下为操作过程：

1.获取centos-template的uuid

[root@xenserver-test ~]# xe vm-list | grep -B 1 centos-template
<centos-template uuid>

2.修改内核启动方式，并传递自定义参数

[root@xenserver-test ~]# xe vm-param-set uuid=<centos-template uuid> HVM-boot-policy=""
[root@xenserver-test ~]# xe vm-param-set uuid=<centos-template uuid> PV-bootloader="pygrub"
[root@xenserver-test ~]# xe vm-param-set uuid=<centos-template uuid> PV-args="_hostname=centos-template _ipaddr=192.168.0.121 _netmask=255.255.255.0 _gateway=192.168.0.1"

3.启动centos-template

[root@xenserver-test ~]# xe vm-start vm=centos-template

4.获取自定义参数

[root@centos-template ~]# cat /proc/cmdline

5.定义初始化脚本

[root@centos-template ~]# cat /etc/rc.local

6.创建具体的脚本

[root@centos-template ~]# touch /root/bootstrap.sh
[root@centos-template ~]# chmod +x /root/bootstrap.sh
[root@centos-template ~]# vim /root/bootstrap.sh

bootstrap.sh如下：

#!/bin/bash
#
# Bootstrap Script for Hostname,Network...
#
# Author: Dong Guo
# Last Modified: 2013/10/24 by Dong Guo

options=$(cat /proc/cmdline|sed 's/.*rhgb quiet  //g')
config=/etc/sysconfig/network-scripts/ifcfg-eth0
failed=/root/bootstrap.failed

function check_root(){
  if [ $EUID -ne 0 ]; then
    echo "This script must be run as root"
    exit 1
  fi
}

function configure_os(){
  echo "DEVICE=eth0" > $config
  echo "ONBOOT=yes" >> $config
  echo "BOOTPROTO=none" >> $config
  
  for i in $options
  do
    option=$(echo $i|cut -d "=" -f 1)
    value=$(echo $i|cut -d "=" -f 2)
    if [ "${option:0:1}" = "_" ]; then
      case "$option" in
        _hostname)
         oldname=$(hostname)
         newname=$value
         sed -i s/"$oldname"/"$newname"/g /etc/sysconfig/network
         hostname $newname
        ;;
        _ipaddr)
         echo "IPADDR=$value" >> $config
        ;;
        _netmask)
         echo "NETMASK=$value" >> $config
        ;;
        _gateway)
         echo "GATEWAY=$value" >> $config
        ;;
      esac
    fi
  done
}

function restart_network(){
  /etc/init.d/network restart
}

function check_status(){
  gateway=$(grep -w GATEWAY $config|cut -d "=" -f 2)
  route -n | grep -wq $gateway
  if [ $? -eq 0 ]; then
    sed -i /bootstrap/d /etc/rc.local
    if [ -a $failed ]; then
      rm -f $failed
    fi
  else
    touch $failed
  fi
}

check_root
configure_os
restart_network
check_status

7.查看脚本

[root@centos-template ~]# ls
anaconda-ks.cfg bootstrap.sh install.log install.log.syslog

8.退出centos-template

[root@centos-template ~]# exit

9.关闭centos-template

[root@centos-template ~]# xe vm-shutdown vm=centos-template

10.获取xenserver-test本地存储的uuid

[root@xenserver-test ~]# xe sr-list | grep -A 2 -B 3 xenserver-test | grep -A 4 -B 1 "Local Storage"
<Local Storage uuid>

11.复制创建新的VM vm-host-1

[root@xenserver-test ~]# xe vm-copy new-name-label=vm-host-1 vm=vm-template sr-uuid=<new uuid>
<new uuid>

12.获取vm-host-1的uuid

[root@xenhost1 ~]# xe vm-list | grep -A 1 <new uuid>

13.传递自定义参数

[root@xenhost1 ~]# xe vm-param-set uuid=<new uuid> PV-args="_hostname=vm-host-1 _ipaddr=192.168.0.122 _netmask=255.255.255.0 _gateway=192.168.0.1"

14.启动vm-host-1

[root@xenserver-test ~]# xe vm-start vm=vm-host-1

15.登录vm-host-1

[root@xenserver-test ~]# ssh root@192.168.1.122

16.查看初始化脚本标记是否被移除

[root@vm-host-1 ~]# cat /etc/rc.local

17.OK！

[root@vm-host-1 ~]# ls
anaconda-ks.cfg bootstrap.sh install.log install.log.syslog  

18.退出vm-host-1

[root@vm-host-1 ~]# exit

创建Windows7

环境介绍：

xenserver-test:192.168.0.37（一台XenServer主机）
centos-template:192.168.0.121（事先创建好的VM）
vm-host-1:192,168.0.122（将要创建的VM）

以下为操作过程：

1.获取win7-template的uuid

[root@xenserver-test ~]# xe vm-list | grep -B 1 win7-template

2.修改内核启动方式，并传递自定义参数

[root@xenserver-test ~]# xe vm-param-set uuid=<centos-template uuid> HVM-boot-policy=""
[root@xenserver-test ~]# xe vm-param-set uuid=<centos-template uuid> PV-bootloader="pygrub"
[root@xenserver-test ~]# xe vm-param-set uuid=<centos-template uuid> PV-args="_hostname=centos-template _ipaddr=192.168.0.121 _netmask=255.255.255.0 _gateway=192.168.0.1"
