Installation Parameters

  • email – The Admin Email Address
  • beta – If there is a newer version of Virtualizor available and you would like to test it then please add beta=true as a parameter
  • license – In case you are installing Virtualizor on internal network you will need to provide the VALID license key. To get internal license key you will need to open a support ticket.

The installation will begin immediately. It may seem that the installation has stopped, if your network speed is slow, but please let it continue. You will see something like this :

After the installation is completed you will be asked to reboot.

You can then visit the Admin Panel to create Virtual Servers and also manage your server.

Note : A log file of the installation process will be created – /root/virtualizor.log


To login to the Softaculous Virtualizor Admin Panel, visit the following URL :


Login with the servers root details.

Admin Panel

After you login, you will see the Admin Panel Dashboard :


Virtualizor uses ports from 4081 – 4085. If there is any firewall restricting this, you will need to allow these ports.

iptables -I INPUT 1 -p tcp -m tcp --dport 4081:4085 -j ACCEPT
NOTE: If you are going to use Webuzo templates for VM creation, please allow ports 2002-2005

Trouble Shoot

NOTE : In all cases please remember to disable SElinux

Cant open http://IP-Address:4084

Please check if your iptables firewall is running You can disable it with the following command if even after allowing ports, the panel is not working :

root> service iptables stop

VPS Doesn’t start

Please check that the correct kernel has been booted.

root> uname -a

ALSO check that quota is disabled in Linux and OpenVZ has its own Quota management system and it will conflict if the OS’s quota is enabled.

root> quotaoff -vaug

Cannot SSH to VPS

The IP must not be added to the Server. You can check if the IP is on the server with the following command :

root> ifconfig

If the IP is there e.g. in eth0:x you will have to remove it. To remove it :

root> rm -rf /etc/sysconfig/network-scripts/ifcfg-eth0:* 
root> service network restart

You shall now be able to SSH to your new VPS.
