|/||80-100 GB||Root partition containing all Hardware Node operating system files, OS templates and ISOs|
|SWAP||4 GB +||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.
Open a Shell Terminal (e.g. PuTTY) and SSH to your server. Run the following commands:
wget -N http://files.virtualizor.com/install.sh chmod 0755 install.sh ./install.sh email@example.com kernel=kvm
Please give the email address correctly !
- email - The Admin Email Address
- kernel - In this case its kvm
- noos - If you dont want to download the DomU operating system for the DomU then please add noos=true as a parameter
- 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
- nested_virt - If you want to enable Nested Virtualization on your server then please add nested_virt=1 as a parameter. If you enable this, it will install a new kernel for enabling nested virtualization. (NOTE: This feature is in BETA at the moment)
- lvg (optional) - If you are going to use LVM for the VPS storage. The Volume Group that will be used for the DomU (VPS) storage e.g. defaults to vg. It should have some OR ALL unallocated space to create LVMs for the VPS.
- interface - You can specify the default interface that you want to set. If not provided it will be considered as eth0.
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 the Storage and the 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.
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.
Before creating any VMs, its necessary to define your storage.
Navigate to Virtualizor Admin Panel -> Storage -> Add Storage
You will see the following wizard :
Fill in the details and define the storage.

root> service virtnetwork restart
Start Command :
root> service virtnetwork start
Stop Command :
root> service virtnetwork stop
NOTE : In all cases please remember to disable SElinux. The Virtualizor installer will try to disable it. For KVM make sure that VT is enabled from bios so VPS can be able to started .
