สร้าง VM (เป็นตัวอย่าง)
I want to use CentOS 5 in my virtual machines, so I download a CentOS 5 template:
# cd /vz/template/cache
# wget http://download.openvz.org/template/precreated/centos-5-x86.tar.gz
I will now show you the basic commands for using OpenVZ.
To set up a VPS from the default CentOS 5 template, run:
# vzctl create 101 --ostemplate centos-5-x86 --config basic
The 101 must be a uniqe ID - each virtual machine must have its own unique ID. You can use the last part of the virtual machine's IP address for it. For example, if the virtual machine's IP address is 192.168.0.101, you use 101 as the ID.
# vzctl set 101 --onboot yes --save
To set a hostname and IP address for the vm, run:
# vzctl set 101 --hostname test.example.com --save
# vzctl set 101 --ipadd 192.168.0.101 --save
Next we set the number of sockets to 120 and assign a few nameservers to the vm:
# vzctl set 101 --numothersock 120 --save
# vzctl set 101 --nameserver 8.8.8.8 --nameserver 8.8.4.4 --nameserver 145.253.2.75 --save
(Instead of using the vzctl set commands, you can as well directly edit the vm's configuration file which is stored in the /etc/vz/conf directory. If the ID of the vm is 101, then the configuration file is /etc/vz/conf/101.conf.)
To start the vm, run
# vzctl start 101
To set a root password for the vm, execute
# vzctl exec 101 passwd
You can now either connect to the vm via SSH (e.g. with PuTTY), or you enter it as follows
# vzctl enter 101
To leave the vm's console, type
# exit
To stop a vm, run
# vzctl stop 101
To restart a vm, run
# vzctl restart 101
To delete a vm from the hard drive (it must be stopped before you can do this), run
# vzctl destroy 101
To get a list of your vms and their statuses, run
# vzlist -a
[root@server1 cache]# vzlist -a
CTID NPROC STATUS IP_ADDR HOSTNAME
101 14 running 192.168.0.101 test.example.com
[root@server1 cache]#
To find out about the resources allocated to a vm, run
# vzctl exec 101 cat /proc/user_beancounters
[root@server1 cache]# vzctl exec 101 cat /proc/user_beancounters

The failcnt column is very important, it should contain only zeros; if it doesn't, this means that the vm needs more resources than are currently allocated to the vm. Open the vm's configuration file in /etc/vz/conf and raise the appropriate resource, then restart the vm.
To find out more about the vzctl command, run
# man vzctl
