Virtual machine

In this section, we describe how to create a virtual machine (VM) in Open Virtual Appliance (OVA) format with the Wazuh server, dashboard, and indexer components pre-installed. The wazuh-virtual-machines/ova/generate_ova.sh script automates the creation of the VM. The VM works with any hypervisor, allowing quick setup of a single-node Wazuh deployment.

Requirements

You need a system with a minimum of 4 CPU cores and 8 GB of RAM to build the virtual machine. Ensure that these dependencies are installed on the system:

Creating the Wazuh VM

Follow the steps below to create the Wazuh virtual machine:

  1. Clone the wazuh-virtual-machines repository and navigate to the ova/ directory. Select the version, for example, v4.14.0.

    $ git clone https://github.com/wazuh/wazuh-virtual-machines && cd wazuh-virtual-machines/ova/ && git checkout v4.14.0

  2. Execute the generate_ova.sh script to create the VM.

    $ ./generate_ova.sh

The above command builds a VM with Wazuh central components. It uses production packages by default. If you are building a pre-release version, you must select the development package dev instead.

$ ./generate_ova.sh -r dev

The -r or --repository option selects the stage to use for the packages. For example:

  • prod: Packages released for production environments.

  • dev: Pre-release packages for testing and development purposes.

The generated virtual machine can be found in the /wazuh-virtual-machines/ova/output directory in .ova format.

Run the following command to check all available options:

$ ./generate_ova.sh -h

Usage: packages/generate_package.sh [OPTIONS]
