Operations on Virtual Machines and Containers 64
Performing Container-Specific
Operations
This section provides the description of operations specific for your Containers.
Setting Name for Container
You can assign an arbitrary name to your Container and use it, along with the Container ID, to
refer to the Container while performing this or that Container-related operation on the server.
For example, you can start or stop a Container by specifying the Container name instead of its
ID.
You can assign names to your Containers using the --name option of the pctl set
command. For example, to set the computer1 name for Container 101, you should execute the
following command:
# pctl set 101 --name computer1 --save
Name computer1 assigned
Saved parameters for Container 101
You can also set a name for Container 101 by editing its configuration file. In this case you
should proceed as follows:
1 Open the configuration file of Container 101 (/etc/vz/conf/101.conf) for editing
and add the following string to the file:
NAME="computer1"
2 In the /etc/vz/names directory on the server, create a symbolic link with the name of
computer1 pointing to the Container configuration file. For example:
# ln --symbolic /etc/vz/conf/101.conf /etc/vz/names/computer1
When specifying names for Containers, please keep in mind the following:
 Names may contain the following symbols: a-z, A-Z, 0-9, underscores (_), dashes (-),
spaces, the symbols from the ASCII character table with their code in the 128 - 255 range,
and all the national alphabets included in the Unicode code space.
 Container names cannot consist of digits only; otherwise, there would be no way to
distinguish them from Container IDs.
 If it contains one or more spaces, the Container name should be put in single or double
quotes.
After the name has been successfully assigned to Container 101, you can start using it instead of
ID 101 to perform Container-related operations on the Node. For example:
 You can stop Container 101 with the following command:
# pctl stop computer1
Stopping Container ...
Container was stopped
Container is unmounted
 You can start Container 101 anew by issuing the following command:
# pctl start computer1
Starting Container ...
