Install OpenVZ. Note: Ubuntu Versions later than 8.04 do not support openvz. Version 11.10 is 3.0, whereas openvz only supports version 2.6, therefore, if you want to re-compile the kernel to install openvz, the kernel cannot exceed 2.6. The following is an installation of the 10.04server version. The 10.04 kernel is another virtualization technology of Linux 2.6: Kvm, VMware, Virtualbox, Xen, and Qemu.

Installation document:
Install openvz in Ubuntu 8.04 or earlier versions:
1) Change the default ubuntu Shell from Dash to Bash.
$ Ln-sf/bin/bash/bin/sh
2) Disable AppArmor
$/Etc/init. d/apparmor stop
$ Update-rc.d-f apparmor remove
$ Apt-get remove apparmor-utils
3) install OpenVZ
$ Apt-getinstall linux-openvz vzctl vzquota
Install openvz in version 10.04 (you need to re-compile the Linux kernel with the openvz patch ):
1) install openvz
2) create a VM
A. Download the ubuntu 10.04 system template:
$ Wget http://download.openvz.org/template/precreated/ubuntu-10.04-x86.tar.gz
$ Music ubuntu-10.04-x86.tar.gz/var/lib/vz/template/cache/
B. Create a VM:
$ Vzctl create101-ostemplate ubuntu-10.04-x86
101 is the virtual machine number, and the id below 100 is used internally in openvz.
By default, virtual machines are created under/var/lib/vz/private/101 /.
The configuration file is in/etc/vz/conf/101. conf.
C. Modify the VM Configuration:
Method 1: directly modify the configuration files in the/etc/vz/conf/directory.
Method 2: Use the vzctl command to modify the modification (which can take effect in real time ).
Set the host name to test.mytest.com and the IP address to 192.168.2.100:
$ Vzctl set 101 -hostnametest.mytest.com-save
$ Vzctl set 101-ipadd192.168.2.100-save
Set the number of sockets allowed to 480
$ Vzctl set 101-numothersock‑save
Set DNS server address
$ Vzctl set 101 -- nameserver192.168.1.101 -- nameserver 8.8.8.8 -- save
D. Use a virtual machine
Enable Virtual Machine: vzctl start 101
Restart the VM: vzctl restart 101
Enter Virtual Machine: vzctl enter 101
Exit VM: exit
Stop Virtual Machine: vzctl stop 101
Delete Virtual Machine: vzctl destroy 101
