Yum install-y centos-release-xen Xen

Installing the Virtualization Management tool

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

Reboot, Xen kernel running

Virtual machine installation Environment build:

1. Configure the Bridging network

(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 ")

4. Install the httpd and place the image under HTML

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--disk path=/xen/zyt_vm01.img,size=6-l http://192.168.16.253/iso

CP a virtual machine:

1. Create a Xen virtual machine configuration file

[email protected] 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"

[email protected] xen]# cat xmexample1|egrep-v ' (^#|^\ *$) ' >zyt_vm02

[Email protected] xen]# VI zyt_vm02

[email protected] 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"

[Email protected] xen]#

2.CP Mirroring

[Email protected] ~]# cd/xen/

[email protected] xen]# LL

Total 1516148

-rwxr-xr-x. 1 root root 6442450944 Mar 6 05:01 zyt_vm01.img

[email protected] xen]# CP zyt_vm01.img ZYT_VM02.IMG

[Email protected] xen]#

3. Start a new virtual machine

XM Create-c zyt_vm02

4. Change the MAC address after entry, host name
