vzquota

This command is used to configure and see disk quota statistics for Containers. vzquota is also
used to turn on the possibility of using per-user/group quotas inside the Container. It allows you to
configure per-user or per-group quota inside the Container as well. vzctl uses vzquota
internally to configure quotas and you usually do not have to use vzquota except for checking the
current quota statistics. The syntax of vzquota command is as follows:
vzquota [options] command <CT_ID> [command-options]
General options available to all vzquota commands are:
-v Verbose mode.
-q Quiet mode. 

[root@tester ~]# vzquota -v show 50 -t
vzquota : (warning) Quota is running, so data reported from quota file may not reflect current values
   resource          usage       softlimit      hardlimit    grace
  1k-blocks         886472        20000000       20000000
     inodes          19529          200000         220000

User/group quota: off,inactive
Ugids: loaded 0, total 0, limit 0
Ugid limit was exceeded: no

User/group grace times and quotafile flags:
 type block_exp_time inode_exp_time  dqi_flags
 user                                       0h
group                                       0h


[root@tester ~]# vzquota -v stat 50
   resource          usage       softlimit      hardlimit    grace
  1k-blocks         844332        20000000       20000000
     inodes          19573          200000         220000

vzquota understands the following commands:
init Before you can use quota, the current disk space and inode usage should be counted. For
the init command, you must specify all the limits as well as the file tree where you want
to initialize the quota.
drop Removes the quota file.
on Turns on quota accounting on the specified quota ID.
off Turns off quota accounting on the specified quota ID.
setlimit Allows you to change quota limits for the running quota.
setlimit2 Set the second-level quota parameters.
stat Shows quota statistics for the running quota.
show Shows quota usage from the quota file

Configures new changed hardware with out reboot (KUDZU)

This hardware probing tool run in a server when we boot the system to configure a new hardware. It then determines if the new hardware is added to/removed from the system by checking the database file /etc/sysconfig/hwconf. If the file exists in the system, then Kudzu detects the new hardware , updates the database file and brings the system intact. If the database file does not exist, it check for the configured devices/hardware in the /etc/modprobe.conf, /etc/sysconfig/network-scripts/ and /etc/X11/xorg.conf.  

You can configure a service for multiple run levels with a single command. For example, /sbin/chkconfig --level 345 kudzu off will disable kudzu for run levels 3, 4, and 5 or /usr/sbin/chkconfig kudzu off.   If you need to edit the Kudzu  you will have to edit this file where the scripts are: /etc/init.d/kudzu

 use man kudzu for more details. 

eg : kudzu -p

Virtuzzo command line

General utilities are intended for performing day-to-day maintenance tasks:

vzctl 

Utility to control Containers.

vzlist

Utility to view a list of Containers existing on the Node with additional information.

vzquota

Utility to control Parallels Virtuozzo Containers disk quotas.

Licensing utilities allow you to install a new license, view the license state, generate a license
request for a new license:

vzlicview

Utility to display the Parallels Virtuozzo Containers license status and parameters.

vzlicload

Utility to manage Parallels Virtuozzo Containers licenses on the Node.

vzlicupdate

Utility to activate the Parallels Virtuozzo Containers installation,update the Parallels Virtuozzo Containers licenses installed on the
