Installing the Opmantek VM

Quick Setup

Keep Me

This accordion item is added so the tabs start closed because by default the top item is open.

Install

1. Download the Opmantek Virtual Machine

If you haven’t already, hit the download button above and download the Opmantek Virtual Machine.

The virtual machine comes as an uncompressed .ova (Open Virtual Appliance) package, just over 1GB in size. Unless you have specific needs, we recommend you download the latest build.

2. Open your hypervisor

A hypervisor is a piece of software used to run virtual machines. Opmantek provides instructions for running our Virtual Machine on most popular hypervisors—but if you’ve never used a hypervisor before, we recommend the free VirtualBox solution, which you can download here.

3. Deploy the Opmantek Virtual Machine

The specific method of deploying the Opmantek Virtual Machine depends on your hypervisor. This page offers installation guides for VirtualBox and VMware Desktop Applications.

If you are deploying on another hypervisor, please use the appropriate guide:

If you have the VM already deployed you can jump to the next section – here.

3a. Deploy on VMware

Go to File –> Open and select the Opmantek Virtual Machine .ova package you just downloaded. The Virtual Machine should import with all settings automatically.

Ensure that you have granted Accessibility permissions in System Preferences for VMware to allow the Virtual Machine to run properly.

4. Run the Virtual Machine

Now that you’re all set up, you’re ready to run the Virtual Machine. In VMWare’s Desktop applications, this is done by pressing the triangular “Play” button.
You can jump to the next step here.

3b. Deploy on VirtualBox

This guide shows screenshots of the macOS version of VirtualBox (6.1). For Windows and Linux equivalent screenshots, please visit the Opmantek Wiki here.

VM Guide 01 - 700

In VirtualBox, go to File>Import Appliance, and then select the Opmantek Virtual Machine .ova package you just downloaded. Select the Opmantek Virtual Machine once it’s loaded into the left sidebar of the application. Then, click on the yellow “Settings” cog. You will need to change four separate settings to allow the Opmantek Virtual Machine to run correctly. The first setting we’ll change can be found under the System tab. You need to ensure that the hardware clock is in UTC time, as below:

You can set a custom name for any node, and enter the IP address, SNMP type and SNMP community. There are also lists of select Locations and Groups which you can use to classify your nodes.
