安装xen

yum install -y centos-release-xen xen

安装虚拟化管理工具

yum install libvirt python-virtinst libvirt-daemon-xen   bridge-utils -y

重启，xen内核运行

虚拟机安装环境搭建：

1.配置桥接网络

[root@localhost xen]# cat xend-config.sxp |egrep -v '(^#|^\ *$)'
(xend-unix-server yes)
(xend-relocation-server no)
(xend-relocation-hosts-allow '^localhost$ ^localhost\\.localdomain$')
(network-script /bin/true)
(vif-script vif-bridge)
(dom0-min-mem 256)
(enable-dom0-ballooning yes)
(total_available_memory 0)
(dom0-cpus 0)
(vncpasswd '')
修改为：

[root@localhost xen]# cat xend-config.sxp |egrep -v '(^#|^\ *$)'
(xend-unix-server yes)
(xend-relocation-server no)
(xend-relocation-hosts-allow '^localhost$ ^localhost\\.localdomain$')
(network-script 'network-bridge bridge=xenbr1')
(network-script /bin/true)
(vif-script vif-bridge)
(dom0-min-mem 256)
(enable-dom0-ballooning yes)
(total_available_memory 0)
(dom0-cpus 0)
(vncpasswd '')
[root@localhost xen]#
2.设置服务器启动

chkconfig libvirtd on
chkconfig libvirt-guest on
chkconfig libvirt-guests on

3.重启后：

[root@localhost xen]# ifconfig

4.安装httpd，并且把镜像放到html下
yum install httpd
mkdir /var/www/html/iso
mount /dev/cdrom1 /var/www/html/iso/
service iptables stop
service httpd start
mkdir /xen

virt-install -n zyt_vm01 -r 512 --disk path=/xen/zyt_vm01.img,size=6 -l http://192.168.16.253/iso

cp一个虚拟机：
1.创建一个xen虚拟机配置文件
[root@localhost xen]# cat xmexample1|egrep -v '(^#|^\ *$)'
kernel = "/boot/vmlinuz-2.6.10-xenU"
memory = 64
name = "ExampleDomain"
vif = [ '' ]
disk = [ 'phy:hda1,hda1,w' ]
root = "/dev/hda1 ro"
extra = "4"
[root@localhost xen]# cat xmexample1|egrep -v '(^#|^\ *$)'>zyt_vm02
[root@localhost xen]# vi zyt_vm02
[root@localhost xen]# cat zyt_vm02
#kernel = "/boot/vmlinuz-2.6.10-xenU"
memory = 512
name = "zyt_vm02"
vif = [ 'bridge=xenbr1' ]
disk = [ 'file:/xen/zyt_vm02.img,xvda,w' ]
#root = "/dev/hda1 ro"
#extra = "4"
[root@localhost xen]#
2.cp镜像
[root@localhost ~]# cd /xen/
[root@localhost xen]# ll
total 1516148
-rwxr-xr-x. 1 root root 6442450944 Mar 6 05:01 zyt_vm01.img
[root@localhost xen]# cp zyt_vm01.img zyt_vm02.img
[root@localhost xen]#

3.启动新的虚拟机
xm create -c zyt_vm02

4.进入后修改mac地址，主机名
