Centos6.4 install xen

Centos6.4 install xen

Install xen

Yum install-y centos-release-xen

Install virtualization management tools

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

Restart and run the xen Kernel

Virtual Machine installation environment setup:

1. Configure the bridging Network

[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 '')

To:

[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 = 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. Set server startup

Chkconfig libmongod on

Chkconfig libvirt-guest on

Chkconfig libvirt-guests on

3. After restart:

[Root @ localhost xen] # ifconfig

4. Install httpd and put the image in 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 512 -- disk path =/xen/zyt_vm01.img, size = 6-l http: // 192.168.16.253/iso

Cp:

1. Create an xen virtual machine configuration file

[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 Image

[Root @ localhost ~] # Cd/xen/

[Root @ localhost xen] # ll

Total 1516148

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

[Root @ localhost xen] # cp zyt_vm01.img zyt_vm02.img

[Root @ localhost xen] #

3. Start a new Virtual Machine

Xm create-c zyt_vm02

4. Modify the mac address and host name after entering
