Install Virtuozzo Linux using Text Mode
This tutorial explains the steps to install Virtuozzo Linux 8 using the text mode and the steps to boot it into the rescue mode.


Virtuozzo is a privately owned software company specializing in virtualization software. Virtuozzo developed the first commercially available OS-level virtualization container technology in 2000, which was then open-sourced in the year 2005 in the form of OpenVZ Virtualization. Virtuozzo is an operating system-level server virtualization solution designed to centralize server management and consolidate workloads by reducing the required number of physical servers. Companies mainly use Virtuozzo for server consolidation, server workload agility, and disaster recovery. Virtuozzo does not generate a virtual machine on a host operating system like traditional virtual machine software. Still, instead, it creates isolated virtual private servers (VPSs) on a single physical server. For instance, the software can run multiple Linux virtual private servers but not Linux and Windows simultaneously on the same server. Each virtual private server (VPS) performs exactly like a stand-alone server and can be rebooted independently in Virtuozzo.
Virtuozzo Linux 8 is a one-to-one (1:1) clone of Redhat Enterprise Linux (RHEL) 8. It is free to download, manage, and distribute.
The purpose of Virtuozzo Linux is to assist companies and their clients with an easy path to move or upgrade the existing estate from CentOS, which has been announced to have a reduced lifecycle. In this tutorial, we will learn the steps to install Virtuozzo Linux 8 using the text mode and the steps to boot it into the rescue mode.
