Virtuozzo Hybrid Server

Virtuozzo Hybrid Server Overview

Virtuozzo is a bare-metal virtualization solution that includes container virtualization, KVM-based virtual machines, software-defined storage along with enterprise features and production support. It runs on top of Virtuozzo Linux, a RHEL-based Linux distribution.

Requirements for Standalone Installations

The recommended hardware requirements for running Virtuozzo Hybrid Server as a standalone installation are as follows:

  • x86-64 platform with hardware virtualization support: Intel VT-x (with “unrestricted guest”)

To check if the Intel processor supports the “unrestricted guest” feature:

* get_app Download from:

* Run python | grep -i unrest. The result must be yes.

  • CPU: at least 4 cores, a 64-bit processor is required for running 64-bit guest operating systems
  • RAM: 4 GB or more
  • HDD: 64 GB or more
  • SSD (optional): at least 30 GiB (at least 32 GiB with /boot)
  • Network: an Ethernet network adapter and a valid IP address.

The actual number of virtual machines and containers you can run on a physical server and their performance depend on resources they will consume.
