xen 虚拟机操作

sdhgf

虚拟及环境如上篇介绍
虚拟centos6
参考：xen官方wiki
http://grantmcwilliams.com/item/ ... installation-on-xen
1.创建虚拟机的硬盘文件

mkdir /opt/xen/dd if=/dev/zero of=/opt/xen/vm01-centos6.img oflag=direct bs=1M seek=10240 count=1dd if=/dev/zero of=/opt/xen/vm01-centos6-1.img oflag=direct bs=1M seek=5120 count=1

下载centos引导内核文件 和RAM DISK 文件

wget http://192.168.0.51:8088/centos/6/os/x86_64/dvd1/isolinux/vmlinuz -O /boot/vmlinuz-xen-centos6.4wget http://192.168.0.51:8088/centos/ ... isolinux/initrd.img -O /boot/initrd-xen-centos6.4
CentOS5版本下载定制内核引导http://192.168.0.51:8088/centos/5/os/x86_64/dvd1/images/xen/

下载xen 安装的配置文件，运行的配置文件

wget http://192.168.0.51:8088/files/xen-centos6-x86_64-install -O /etc/xen/vm01-centos6-installwget http://192.168.0.51:8088/files/xen-centos6-x86_64 -O /etc/xen/vm01-centos6

安装

xm create vm01-centos6-install -c

启动

xm create vm01-centos6 -c

安装的配置文件 vm01-centos6-install

kernel = "/boot/vmlinuz-xen-centos6.4"ramdisk = "/boot/initrd-xen-centos6.4"name = "vm01-centos"memory = "1024"disk = [ 'file:/opt/xen/vm01-centos6.img,xvda,w', ]vif = [ 'mac=00:16:36:04:7f:e1,bridge=xenbr0,script=vif-bridge', ]extra = "text ks=http://192.168.0.51:8088/files/kickstart-centos6-x86_64.cfg"vcpus=2on_reboot = 'destroy'on_crash = 'destroy'

启动配置文件 vm01-centos6
添加了一块5G硬盘xvdb，一块网卡mac”00:16:36:05:7f:e2″

name = "vm01-centos"memory = "1024"disk = [ 'file:/opt/xen/vm01-centos6.img,xvda,w','file:/opt/xen/vm01-centos6-1.img,xvdb,w', ]vif = [ 'mac=00:16:36:04:7f:e1,bridge=xenbr0,script=vif-bridge','mac=00:16:36:05:7f:e2,bridge=xenbr0,script=vif-bridge', ]bootloader="/usr/bin/pygrub"vcpus=2on_reboot = 'restart'on_crash = 'restart'

自动安装配置文件 kickstart-centos6-x86_64.cfg

创建vm02-centos

cp /opt/xen/vm01-centos6.img /opt/xen/vm02-centos6.imgcp /etc/xen/vm01-centos6 /etc/xen/vm02-centos6dd if=/dev/zero of=/opt/xen/vm01-centos6-1.img oflag=direct bs=1M seek=5120 count=1

修改/etc/xen/vm02-centos6

name = "vm02-centos"memory = "1024"disk = [ 'file:/opt/xen/vm02-centos6.img,xvda,w','file:/opt/xen/vm02-centos6-1.img,xvdb,w', ]vif = [ 'mac=00:16:36:04:7f:e3,bridge=xenbr0,script=vif-bridge','mac=00:16:36:05:7f:e4,bridge=xenbr0,script=vif-bridge', ]bootloader="/usr/bin/pygrub"vcpus=2on_reboot = 'restart'on_crash = 'restart'

xm create vm02-centos6 -c

进入vm02-centos系统修改网卡eth0/1 的mac,uuid值,ifup eth0/1即可使用。

添加至开机启动

ln -sv /etc/xen/vm01-centos6 /etc/xen/auto/ln -sv /etc/xen/vm02-centos6 /etc/xen/auto/

查看虚拟机列表

xm list

连接管理

xm console vm01-centos6

ctrl+] 命令切换至Domain0

基本就这样了！

虚拟windows
这玩意儿和系统内核不同，必须要使用HVM引导方式启动看装，╮(╯▽╰)╭，CPU不支持，等买了实验用的服务器再搞
基本的安装模式是这个样子的

import os, re
arch = os.uname()[4]
if re.search(’64′, arch):
   arch_libdir = ‘lib64′
else:
   arch_libdir = ‘lib’
# HVM loader
kernel = “/usr/lib/xen/boot/hvmloader”
builder=’hvm’
device_model = ‘/usr/lib/xen/bin/qemu-dm’
# memory can’t be much higher than this; known limitation
memory = 768
name = “freebsd”
vif = [ 'mac=00:16:36:04:7f:e7,bridge=xenbr0,script=vif-bridge','mac=00:16:36:05:7f:e8,bridge=xenbr0,script=vif-bridge', ]
disk = [
       'file:/opt/xen/freebsd/vm04-freebsd.img,xvda,w',
       'file:/opt/xen/freebsd/FreeBSD-9.1-RELEASE-amd64-bootonly.iso,hdc:cdrom,r'
]
# make sure we boot from cdrom here 启动顺序光盘硬盘软盘
boot=”dcf”
#apic=1
apic=0
#acpi=1
acpi=0
#为了保证安装的顺利，暂时先将ACPI和APIC先关闭
pae=1
vcpus=2
serial = “pty” # enable serial console
on_poweroff = ‘destroy’
on_reboot   = ‘restart’
on_crash    = ‘restart’
vnc=1
vncunused=1
#首先要设定vncunused这条设定项为值1。意思是，让宿主使用未占用的端口为虚拟机分配VNC端口
#vncdisplay=1
vnclisten=’0.0.0.0′
