Installing Softaculous Virtualizor for LXC is very simple.


  • CentOS 7.x
  • yum / apt-get
  • Storage to create the VPS (DomUs) disks

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 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 its recommended to have an empty Volume Group.


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

wget -N
chmod 0755
./ kernel=lxc

Please give the email address correctly ! NOTE : LXC is in Beta. It is not recommended for production Servers at the moment.

Installation Parameters

  • email - The Admin Email Address
  • kernel - In this case its lxc
  • noos - If you dont 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.
