Below are the steps on how to increase disk quota of a virtual server running on openvz.
1. Check the disk status of your disk quota.
[root@openvz ~]# vzquota stat 101
[root@openvz ~]# vzquota stat 101
resource usage softlimit hardlimit grace
1k-blocks 631508 2097152 2306867
inodes 29386 200000 220000
2. In this example, I will increase the disk quota twice as the current size. Take note of the soft limit and hard limit.
[root@openvz ~]# vzctl set 101 –diskspace $(( 2097152*2 )):$(( 2306867*2 )) –save
CT configuration saved to /etc/vz/conf/101.conf
3. Restart the vz service to take effect the changes.
[root@openvz ~]# /etc/init.d/vz restart
Suspending CT 101
Bringing down interface venet0: [ OK ]
Stopping OpenVZ: [ OK ]
Starting OpenVZ: [ OK ]
Bringing up interface venet0: [ OK ]
Starting CT 101: [ OK ]
http://webserverpage.com/?p=237
This is in continuation of the link above.
[root@openvz ~]# vzlist -a
CTID NPROC STATUS IP_ADDR HOSTNAME
101 12 running 192.168.2.127 subopenvz.com
Backup/Restore Openvz VMs with vzdump on CentOS
1. Download and install cstream as it is a depedency for vzdump.
http://pkgs.repoforge.org/cstream/
wget http://pkgs.repoforge.org/cstream/cstream-2.7.4-3.el6.rf.i686.rpm
rpm -Uvh cstream-2.7.4-3.el6.rf.i686.rpm
2. Download and install vzdump.
http://download.openvz.org/contrib/utils/vzdump/
wget http://download.openvz.org/contrib/utils/vzdump/vzdump-1.2-4.noarch.rpm
rpm -Uvh vzdump-1.2-4.noarch.rpm
1.2-6 version of vzdump, the location of the modules is not “automatic” so I need to export the location of the PVE libraries that vzdump requires
export PERL5LIB=/usr/share/perl5/
3. It is time to the backup process.
Checked your current VM veid first:
[root@openvz home]# vzlist -a
CTID NPROC STATUS IP_ADDR HOSTNAME
101 12 running 192.168.2.127 subopenvz.com
4. Create a directory where you want to save the backup. Mine is /home/backup.
mkdir /home/backup
vzdump –compress –dumpdir /home/backup –stop 101
/************the result should look like this***********/
[root@openvz backup]# vzdump –compress –dumpdir /home/backup –stop 101

So now you backup files will be located at this path.
[root@openvz backup]# ls
vzdump-openvz-101-2012_12_07-12_44_15.log vzdump-openvz-101-2012_12_07-12_44_15.tgz
To Restore.
Let say the CTID 101 corrupt for some server issues then we can use vzrestore.
yum install vzrestore
cd /home/backup
vzrestore vzdump-openvz-101-yourfilename.tgz 101
Start the vz service to run the restored vm.
[root@openvz private]# service vz restart
Bringing down interface venet0: [ OK ]
Stopping OpenVZ: [ OK ]
Starting OpenVZ: [ OK ]
Bringing up interface venet0: [ OK ]
Starting CT 101: [ OK ]
To uninstall openvz and all the components.
1. To see the list of the packages related to vz.
[root@openvz backup]# rpm -qa | grep vz
vzctl-core-4.1-1
vzquota-3.1-1
vzdump-1.2-4
ovzkernel-2.6.18-308.8.2.el5.028stab101.1
vzkernel-2.6.32-042stab065.3
vzctl-4.1-1
vzkernel-firmware-2.6.32-042stab065.3
ovzkernel-2.6.18-53.1.6.el5.028stab053.6
2. Remove the packages.
[root@openvz backup]# rpm -e vzctl-core-4.1-1 vzquota-3.1-1 vzdump-1.2-4 ovzkernel-2.6.18-308.8.2.el5.028stab101.1 vzkernel-2.6.32-042stab065.3 vzctl-4.1-1 vzkernel-firmware-2.6.32-042stab065.3 ovzkernel-2.6.18-53.1.6.el5.028stab053.6
Follow the steps below.
1. Turn off SELinux
vi /etc/selinux/config
/************************************************************************/
SELINUX=disabled
SELINUXTYPE=targeted
SETLOCALDEFS=0
/************************************************************************/
2. Reboot the machine then type the command below to see the status of the selinux if it is completely disabled.
Reboot
3. Remove the firewall
chkconfig iptables –level 2345 off
chkconfig iptables –list
cd /etc/yum.repos.d
wget http://download.openvz.org/openvz.repo
rpm –import http://download.openvz.org/RPM-GPG-Key-OpenVZ
vi openvz.repo <– to see which repo you want to enable. I just use the rhel5 “[openvz-kernel-rhel5]” as the rhel6 make the kernel of centos 5.6 corrupt. I think rhel6 is for centos 6 and above.

Next is to install a template for the distribution.
You may follow the link below to download your desired template.
http://wiki.openvz.org/Download/template/precreated
cd /vz/template/cache
wget http://download.openvz.org/template/precreated/contrib/centos-5-i386-default.tar.gz
To set up a VPS from the default CentOS 5 template, run:
vzctl create 101 –ostemplate centos-5-i386-default –config vps.basic
Set to start on boot. Type the commands below to the terminal.
vzctl set 101 –onboot yes –save
vzctl set 101 –hostname openvz.com –save
vzctl set 101 –ipadd 192.168.2.127 –save
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 –save
I just use google name server for this example.
vzctl start 101
vzctl exec 101 passwd
You can now connect using ssh or terminal client.
You may also try to upload your website at this location
/vz/private/101/var/www/html
/*****index.html*********/
<html>
<body>
This is my test index file inside my /vz/private/101/var/www/html
</body>

/****end of my code******/
This is my test index file inside my /vz/private/101/var/www/html
then type the ip address that you have assigned in your openvz.
http://192.168.2.127
You may need to have a root access to the main server where the PLESK have been installed.
Please type the command below to show your current password.
[root@centos ]# /usr/local/psa/bin/admin –show-password
sKyMI8DrPa6B
Below is the command to reset the ‘admin’ user password.
[root@centos ]# /usr/local/psa/bin//init_conf -u -passwd
