KLYRN VM
Install free

Install with one command.

Run this as root on a fresh server. The controller is ready in a few seconds.

curl -fsSL https://get.klyrn.com/vm | sudo bash

Ubuntu 22.04 to 26.04, Debian 12 and 13, AlmaLinux and Rocky Linux 8 to 10, CentOS Stream 10. 64-bit Intel or AMD.

From install to a first machine

  1. Install the controller

    The command above checks the release signature, installs the controller and starts it. It prints the address of your panel and a setup token.

  2. Create your account

    Open the address in a browser and use the token to create the first administrator.

  3. Add a compute node

    To use the same server, run klyrn-vm admin node add-local. To use another server, choose Add node in the panel and paste the command it gives you.

Signed updates

You update from the panel with one button.

  • Every release is signed.An update that does not match the signature is refused.
  • The new version is tested first.The controller runs it and checks it before switching over, and keeps the old version.
  • Machines keep running.A compute node updates its agent without touching a guest.
  • Each release is installed first.Before it is offered, it is installed on freshly reinstalled servers. The changelog lists them.

Then set it up.
