centos6.4 安裝xen

centos6.4 安裝xen

安裝xen

yum install -y centos-release-xen xen

安裝虛擬化管理工具

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

重啟，xen核心運行

虛擬機器安裝環境搭建：

1.配置橋接網路

[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 '')

修改為：

[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.設定伺服器啟動

chkconfig libvirtd on

chkconfig libvirt-guest on

chkconfig libvirt-guests on

3.重啟後：

[root@localhost xen]# ifconfig

4.安裝httpd，並且把鏡像放到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一個虛擬機器：

1.建立一個xen虛擬機器組態檔

[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鏡像

[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.啟動新的虛擬機器

xm create -c zyt_vm02

4.進入後修改mac地址，主機名稱
