Creating a Virtuozzo container

Use the following steps to create a Viruozzo container by using the CLI.

1. Check the list of containers on your host.

   [root@vztrain01 ~]# vzlist -a
   
   CTID      NPROC STATUS    IP_ADDR         HOSTNAME
   
   1         93 running   192.168.135.58  ServiceCT
   
   100          9 running   67.228.128.93   vztest01.softlayer.local
   

2. Create a container with an open ID#. The number must be higher than 100 and not already in use. In this example, use 122.

   [root@vztrain01 ~]# vzctl create 122 --pkgset redhat-as3-minimal-x86_64  --config basic
   
   Creating Container private area (redhat-as3-minimal-x86_64/20080630)
   
   Container is mounted
   
   Postcreate action done
   
   Container is unmounted
   
   Container private area created
   
   Container registered succesfully
   
   [root@vztrain01 ~]# vzlist -a
   
      CTID      NPROC STATUS    IP_ADDR         HOSTNAME
   
         1         93 running   192.168.135.58  ServiceCT
   
       100          9 running   67.228.128.93   vztest01.softlayer.local
   
       122          - stopped   -               -
   

   After you create a container, the VZ is in the stopped state. If you are not sure what packages are installed, you can use the vzpkgls command. This command shows you a list of installed Virtuozzo OS and application packages that are on the server. For the example, a Red Hat template is used, but Virtuozzo supports several different operating systems: Red Hat, CentOS, Debian, Fedora Core, and SUSE.

3. Review the default configuration for the container and make necessary changes.

[root@vztrain01 ~]# less /vz/private/122/ve.conf

4. Start the container.

   [root@vztrain01 ~]# vzctl start 122
   
   Starting Container ...
   
   Container is mounted
   
   Setup slm memory limit
   
   Setup slm subgroup (default)
   
   Setting devperms 20002 dev 0x7d00
   
   Adding port redirection to Container(1): 4643 8443
   
        Adding IP address(es):
   
        Configure meminfo: 65536
   
        Container start in progress...
   

   Moments later the container runs. You can check the status again with the vzctl status 122 command.

5. Add parameters that are necessary to manage the container.

        [root@vztrain01 ~]# vzctl set 122 --ipadd 12.34.234.142 --hostname vz122.domain.com --userpasswd root:password123 --save
   
        Hostname for Container set: vz122.domain.com
   
        Adding IP address(es) to pool: 12.34.234.142
   
        Adding IP address(es): 12.34.234.142
   
        Shutting down loopback interface:  [  OK  ]
   
        Setting network parameters:  [  OK  ]
   
        Bringing up loopback interface:  [  OK  ]
   
        Bringing up interface venet0:  [  OK  ]
   
        Changing password for user root.
   
        passwd: all authentication tokens updated successfully.
   
        Saved parameters for Container 122
   

The basic setup of a new Virtuozzo container by using the CLI is complete.
