Get Virtualizor

Installing Softaculous Virtualizor for LXC is very simple. Let's get started!


  • OS Support: CentOS 7.x or AlmaLinux 8.x
  • Package manager: yum / apt-get
  • Storage required: For Container's disk creation, (DomUs) disk is required.
  • If the server is from the panel then install the original/stock kernel from the OVH panel by choosing its checkbox on the last step on the OVH panel while installing OS.

Partition Scheme

Partition Size Description
/ 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 a shortage of real memory)
Storage All the remaining space on the hard disk.  This partition can be used to create Logical Volumes 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 it's recommended having an empty Volume Group.

Supported storage types

( LVM | Thin LVM | ZFS | ZFS Thin | ZFS Compressed | ZFS Thin Compressed )


Open a Shell Terminal (e.g. PuTTY) and SSH to your server. Run the following commands:

wget -N
chmod 0755
./ kernel=lxc
Always provide a valid email address else the installation will fail!

Installation Parameters

  • email - The Admin Email Address
  • kernel - In this case, its lxc
  • noos - If you don't want to download the DomU operating system for the DomU then please add noos=true as a parameter
  • 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.
  • license - In case you are installing Virtualizor on the internal network you will need to provide the VALID license key. To get the 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 :
