AtomOS Hypervisor

The highest performing Linux KVM hypervisor with unrivalled OS support.
Meant for on-prem, available on-cloud for transparent portability.

The next-gen Linux hypervisor you were waiting for

No need to be fancy to be just right

At Elemento we believe the Linux paradigm is the one to follow.
‍
We didn't want to be fancy, implement our virtualisation platform from zero forgetting about all the great stuff people behind KVM and QEMU did in the past 30 years.

We decided to build AtomOS on top of such technologies

Avoiding as much as possible forking and, instead, trying to generate PRs and code contributions as soon as we encountered a missing feature or a bug.

Make it easy, always

Our hypervisor is incredibly easy to handle even for a basic Linux sysadmin. No fancy CLIs included!

RHEL-compliant system

Our system is based on a RHEL-compliant underlying base distro (right now it's Rocky Linux <3) and builds on top of that our discovery-based Infrastructure-as-a-Services (IaaS) platform.

Cutting-edge features with AtomOS

With an intuitive interface and automated management tools, it enables companies to optimize resources and reduce operational costs.

KVM & QEMU

AtomOS adopts standard Linux virtualisation tools. That means that a sysadmin will always be able to run virsh list to list VMs on a host, despite them being created by Elemento's daemons.

RHEL-like hardware compatibility

Since the Linux flavour we are based on is binary-compatible with RHEL, we can offer the same hardware compatibility. And that's huge!

Runs anywhere

AtomOS is engineered to run either on physical servers, as well as on bare metal instances rented from Cloud providers. The choice is yours!

Scalable by design

Using a discovery mechanism based on our patent, we are able to accomplish dynamic VM allocation at hyperscale of that without centralised services such as a matchmaker or an hardware catalog.

Meant for any OS
Meant for VDI
Meant for perfection

AtomOS is built to be able to virtualise any OS.

That means complete support for Linux and Windows on any hardware and (incoming!) MacOS support on Apple hardware.

We couldn't miss that

In addition, we always wanted to be able to do whatever we desired to on our VMs. That means playing at a AAA videogame or designing complex stuff in 3D CAD had to be supported.

Yes, it can run Crysis.

We built into AtomOS (and our client ElectrOS) host-level support for SSH, VNC and RDP.

Let your sysadmins
be sysadmins

Sysadmins are always running against time to fix security flaws and to keep their infrastructures updated.

However, they often need to stop to manually handle VM allocation requests coming from the users via email, tickets, messages, phone calls and many other channels.

Mr. Robot feel

That's why with AtomOS sysadmins will have the choice to keep everything centralised on their hands or to let the end-users able to autonomously allocate their VMs via Electros.

This means your sysadmins will focus on what they are best at

Get the hardware
you want

Atomos Hypervisor enables users to require specific hardware features no other hypervisor is able to expose to the users.

Some of these features include:

  • Make sure the VM gets allocated on a host using ECC memory
  • Dynamically allocate GPU-packed VMs without physical slot addresses
  • Select hosts capable of getting to the VM specific CPU instruction set extensions

Getting AtomOS

AtomOS never reinvents the wheel.
‍
‍This means we are not creating AtomOS as a new Linux distribution, but rather we offer AtomOS as a convenient upgrade for compatible distributions! These installation steps are identical for the free or paid version: the additional enterprise features are activated automatically when you add a valid license key. Follow the few steps beside to get started.

1. Install a supported base OS

To install AtomOS you just need a server or computer running a copy of one of the following supported Linux distributions:

Almalinux 9.xRocky linux 9.xFedora 38+Ubuntu 24.xDebian 12+

We recommend using a clean install, but if you are skilled enough you can start off a running install!

2. Get AtomOS via runnable script

The operations one needs to perform to install AtomOS are available in the script published and maintained

On the compatible base OS open a terminal window and run:
‍
sudo bash -c "curl https://repo.elemento.cloud/get-atomos.sh | bash"

3. Reboot and configure

After the reboot you'll find:
  • All the network interfaces renamed with easy naming
  • A Cockpit-based web interface at port 9090
  • A Linux Bridge network adapter named br0 for VM connectivity
All Elemento server-side daemons will be running on their ports.You just need to configure one or more storage spaces to be visible by Elemento Storage Services (namely mounted at /mnt/ and containing. a settings.json file.

4. Start using Electros and add a license!

Electros can be installed following this guide.

If you need to configure a cluster with many servers, enjoy live monitoring, exploit your hosts with unlimited VMs and much more, just get an AtomOS Enterprise License

Curious about AtomOS?
Check the most FAQs

How does AtomOS work?

Running AtomOS on your system is as easy as downloading the ISO image and booting your selected server or computer off that image directly or burning it to a USB drive. Installing a valid license is as easy as copying on the burned image a license file.

Can I upgrade my Community license to Enterprise?

Yes! A Community copy of AtomOS contains the whole codebase to become easily an Enterprise copy. You'll just need to add a license file downloaded from our portal or our tools and restart the system services belonging to Elemento.

What happens if my Enterprise license expires?

A copy of AtomOS which runs off an expired Enterprise license will simply start working as a Community edition copy, therefore with all the limitations deriving from that.

Am I allowed to modify AtomOS code?

Yes, but our codebase requires you to share such edits with the same community we are sharing the original codebase with, and in particular through the same tools (e.g. GitHub). Any modified code belongs to our company and we are entitled to use such improvements in future release without further notice (quoting the original author!).

What hardware can I run AtomOS on?

We tested AtomOS almost on any modern hardware.That means AMD and Intel consumer, HEDT and server CPUs and even some ARM server processors.While we are confident it will run on any RHEL-supported hardware, we cannot ensure it will run flawlessly on any hardware you might throw at it.In case you want to be safe and get a real plug&play experience you might consider getting a Orbital system.
