xenserver 虚拟机定时开关机实现

1. 在xencenter中创建vapp，并备注为autostart

2. 编辑vapp启动和关机脚本

#!/bin/bash
TAG="autostart"

usage(){
  echo "Usage: $0 [start | shutdown]" 
}

shutvapp(){
  for vapp_uuid in $vapp_uuids
  do
    vapp_tags=`xe appliance-list uuid=$vapp_uuid params=name-description --minimal`
    vapp_oper=`xe appliance-list uuid=$vapp_uuid params=allowed-operations --minimal`
    if [ "$vapp_tags" == "$TAG" ];then
      if [ "$vapp_oper" != "start" ];then
        echo "shutdown vAPP $vapp_uuid"
        xe appliance-shutdown uuid=$vapp_uuid
      else
        echo "the vAPP $vapp_uuid has turned off"
      fi 
    fi
  done
}

startvapp(){
  for vapp_uuid in $vapp_uuids
  do
    vapp_tags=`xe appliance-list uuid=$vapp_uuid params=name-description --minimal`
    vapp_oper=`xe appliance-list uuid=$vapp_uuid params=allowed-operations --minimal`
    if [ "$vapp_tags" == "$TAG" ];then
      if [ `echo "$vapp_oper" |grep -wc start` == 1 ];then
        echo "start vAPP $vapp_uuid"
        xe appliance-start uuid=$vapp_uuid
      else
        echo "the vAPP $vapp_uuid has start"
      fi 
    fi
  done
}

vapp_uuids=`xe appliance-list params=uuid |grep uuid |awk -F": " '{print $2}'`

if [ -z "$1" ]; then
  usage
else
  opration=$1
fi

if [ "$opration" == "start" ];then
  startvapp
elif [ "$opration" == "shutdown" ];then
  shutvapp
else
  usage
fi

3. 通过crontab -e 编辑计划任务文件
