批量创建XEN虚拟机的脚本

  批量创建XEN虚拟机。
     使用方法：   xen_create.sh 虚拟机名(这里定义为VM-XEN-虚拟机名）

1   xen_create.sh

#!/bin/bash
UUID=$(uuidgen)
MAC=$(/opt/macgen.py)
echo name = \"VM-XEN-$1\" >>VM-XEN-$1
echo uuid = \"$UUID\" >>VM-XEN-$1
echo maxmem = 2048 >>VM-XEN-$1
echo memory = 2048 >>VM-XEN-$1
echo vcpus = 1 >>VM-XEN-$1
echo builder = \"hvm\" >>VM-XEN-$1
echo kernel = \"/usr/lib/xen/boot/hvmloader\" >>VM-XEN-$1
echo boot = \"c\" >>VM-XEN-$1
echo pae = 1 >>VM-XEN-$1
echo acpi = 1 >>VM-XEN-$1
echo apic = 1 >>VM-XEN-$1
echo localtime = 0 >>VM-XEN-$1
echo on_poweroff = \"destroy\" >>VM-XEN-$1
echo on_reboot = \"restart\" >>VM-XEN-$1
echo on_crash = \"restart\" >>VM-XEN-$1
echo device_model = \"/usr/lib64/xen/bin/qemu-dm\" >>VM-XEN-$1
echo sdl = 0 >>VM-XEN-$1
echo vnc = 1 >>VM-XEN-$1
echo vncunused = 1 >>VM-XEN-$1
echo keymap = \"en-us\" >>VM-XEN-$1
echo disk = [ \"file:/ddmap/xen/images/VM-XEN-$1.img,hda,w\", \",hdc:cdrom,r\" ] >>VM-XEN-$1
echo vif = [ \"mac="$MAC

2  macgen.py （随机产生MAC地址）

点击(此处)折叠或打开

#!/usr/bin/python
# macgen.py script to generate a MAC address for Red Hat Virtualization guests

import random

def randomMAC():
        mac = [ 0x00, 0x16, 0x3e, random.randint(0x00, 0x7f), random.randint(0x00, 0xff), random.randint(0x00, 0xff) ]
        return ':'.join(map(lambda x: "%02x" % x, mac))

print randomMAC()
