Now when the physical CPU is being utilized to the fullest, the priority of *CPU resources to be assigned to each VM is decided by the CPU Units. Hence of all the CPU Time / Resources available, VPS 101 will get 1/3rd = 1000 / (1000 + 2000) and VPS 102 will get 2/3rd = 1000 / (1000 + 2000) of the CPU resources.

*CPU % : Depending on the number of cores assigned, this is the maximum percentage the VPS can use of the physical core. Lets say your Physical CPU is having 4 cores. If you assign 4 cores to a VPS and set a CPU % of 400% then the VPS will be allowed to use all cores to its 100%. Note : Each CPU core represents 100% of one physical core.

Compatibility

Softaculous Virtualizor is a powerful VPS Management Panel. Virtualizor supports OpenVZ, Xen Paravirtualization, Xen HVM and Linux-KVM virtualization. By using Virtualizor, admins can create a VPS on the fly by the click of a button. VPS users can start, stop, restart and manage their VPS using a very advanced web based GUI. Pre-requisites:

Before installing Virtualizor, we need to make sure few things:

  • First we need to make sure the supported version of Operating System is

installed. Following are the supported OS: CentOS 5.x / 6.x / 7.x or Red Hat Enterprise Linux 5.x / 6.x or Scientific Linux 5.x / 6.x or Ubuntu 12.04 or Ubuntu 14.04 (x86_64) Verify the version of OS by running following command: Cat /etc/issue

  • KVM does not support 32 bit operating system. Therefore, make sure that 64 bit

operating system is installed. Verify the correct installation by executing following command: Uname -a

  • yum / apt-get repository is enabled
  • Make sure that VT is enabled from bios so VPS can be able to started.
  • Disable SElinux
  • Insert non-formatted text hereMake sure that server has enough Storage to create the VPS (DomUs) dis

Requirements

Each Virtualization type has its own requirements. Please refer to the sections below to see the details.

KVM Requirements

Requirements

  • CentOS 5.x / 6.x / 7.x or Red Hat Enterprise Linux 5.x / 6.x or Scientific Linux 5.x / 6.x or Ubuntu 12.04 or Ubuntu 14.04 (x86_64)
  • yum / apt-get
  • Storage to create the VPS (DomUs) disks

Notes : KVM module does not support 32 bit operating system. Please install a 64 bit OS if you want to install KVM. KVM module requires VT enabled from the BIOS to be loaded.

Partition Scheme

Partition Size Description
/ 80-100GB Root partition containing all Hardware Node operating system files, OS templates and ISOs
SWAP 4GB+ Paging partition for the Linux operating system(Swap memory is been used by virtual servers if there is shortage of real memory)
Storage All the remaining space on the hard disk This partition can be used to create either Logical Volumes or File Based Storage for the VPS (DomUs).

NOTE for LVM : You must NOT create any Logical Volume and MOUNT it. This must be an EMPTY VOLUME GROUP. Virtualizor will not delete any pre-existing LVs in the Volume Group. But its recommended to have an empty Volume Group.

NOTE for File Storage : You must create and mount the folder.


OpenVZ Requirements

Requirements

  • CentOS 5.x / 6.x or Red Hat Enterprise Linux 5.x / 6.x or Scientific Linux 5.x / 6.x or Ubuntu 12.04 (x86 or x86_64)
  • yum


Partition Scheme

Partition Size Description
/ 20GB+ Root partition containing all Hardware Node operating system files
SWAP 2 times RAM Paging partition for the Linux operating system
/vz All the remaining space on the hard disk Partition to host OpenVZ templates and Virtual Private Servers

Preparation

Installing Virtualizor is prety simple. This article will guide you through the intallation.

First navigate to your services through Dacentec client area and hit the dedicated server that you want to install Virtualizor. On the left side click "provisioning"

Eldo-2.jpg

Here you will be asked to choose the Operating system, partitioning, hostname etc. For this guide we will use CentOS 6 (latest). Note: Choose the correct partitioning depending on the Virtualization type that you are going to use (OVZ, KVM, XEN)

Eldo-3.jpg

(Be sure that you note your root password.

Once provisioning is done we can continue.

Installation

Installation of Virtualizor is fairly simple. First open a Shell Terminal (e.g. PuTTY) and SSH to your server. Start the installation by executing following command:

For KVM Installation 

     wget -N http://files.virtualizor.com/install.sh
     chmod 0755 install.sh
     ./install.sh [email protected] kernel=kvm

For OpenVZ Installation 

     wget -N http://files.virtualizor.com/install.sh
     chmod 0755 install.sh
     ./install.sh [email protected]

The installation will begin immediately and the given below screen will appear. It may seem that the installation has stopped, if your network speed is slow, but please let it continue.

Eldo-4.jpg

After this the setup will automatically do following steps: - Install PHP, MySQL and Web Server. - Downloading and Installing Virtualizor - Installing the Virtualization kernel – kvm

Eldo-5.jpg

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

Eldo-6.jpg

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

Once Virualizor finally installs, you can access the login by visiting the following URL: 

     https://Your-IP:4085/
     http://Your-IP:4084/
     Your login will be:
     username: your_server_user
     password: your_password

Eldo-7.jpg

DONT FORGER TO DISABLE SELINUX. IF SELINUX IS NOT DISABLED BEFORE THE REBOOT SERVER WILL NOT START

Disable SELinux

Type

vi /etc/selinux/config

using "vi" command will load the file. Press "a" to enter the edit mode and edit SELinux to "disabled" like this.

Storage (KVM Only)

For KVM Virtualization you will need to creat Storage before creating any VPS. Navigate to Virtualizor Admin Panel >> Storage >> Add Storage You will see the following wizard :
