Creating a Virtuozzo container

{: #creating-a-new-virtuozzo-container-cli}

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
   

   {: codeblock}

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   -               -
   

   {: codeblock}

   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

{: codeblock}

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...
   

   {: codeblock}

   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
   

   {: codeblock}

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