This article describes an OT sensor deployment on a virtual appliance using Microsoft Hyper-V.
| Appliance characteristic | Details |
|---|---|
| Hardware profile | As required for your organization. For more information, see Which appliances do I need? |
| Performance | As required for your organization. For more information, see Which appliances do I need? |
| Physical specifications | Virtual Machine |
| Status | Supported |
Note
We recommend using the 2nd Generation configuration, which offers better performance and increased security, for configuration see Microsoft Hyper-V Gen 2.
Important
Versions 22.2.x of the sensor are incompatible with Hyper-V, and are no longer supported. We recommend using the latest version.
Prerequisites
The on-premises management console supports both VMware and Hyper-V deployment options. Before you begin the installation, make sure you have the following items:
Microsoft Hyper-V hypervisor (Windows 10 Pro or Enterprise) installed and operational. For more information, see Introduction to Hyper-V on Windows 10.
Available hardware resources for the virtual machine. For more information, see OT monitoring with virtual appliances.
The OT sensor software downloaded from Defender for IoT in the Azure portal.
Make sure the hypervisor is running.
Note
There is no need to pre-install an operating system on the VM, the sensor installation includes the operating system image.
Create the virtual machine
This procedure describes how to create a virtual machine by using Hyper-V.
To create the virtual machine using Hyper-V:
Create a virtual disk in Hyper-V Manager (Fixed size, as required by the hardware profile).
Select format = VHDX.
Enter the name and location for the VHD.
Enter the required size according to your organization's needs (select Fixed Size disk type).
Review the summary, and select Finish.
On the Actions menu, create a new virtual machine.
Enter a name for the virtual machine.
Select Generation and set it to Generation 1, and then select Next.
Specify the memory allocation according to your organization's needs, in standard RAM denomination (for example, 8192, 16384, 32768). Don't enable Dynamic Memory.
Configure the network adaptor according to your server network topology. Under the "Hardware Acceleration" blade, disable "Virtual Machine Queue" for the monitoring (SPAN) network interface.
Connect the VHDX, created previously, to the virtual machine.
Review the summary, and select Finish.
Right-click on the new virtual machine, and select Settings.
Select Add Hardware, and add a new network adapter.
Select the virtual switch that connects to the sensor management network.
Allocate CPU resources according to your organization's needs.
Select BIOS, in Startup order move IDE to the top of the list, select Apply and then select OK.
Connect the management console's ISO image to a virtual DVD drive.
Start the virtual machine.
On the Actions menu, select Connect to continue the software installation.
Software installation
To start installing the OT sensor software, open the virtual machine console.
The VM starts from the ISO image, and the language selection screen will appear.
Continue with the generic procedure for installing sensor software.
Next steps
Continue understanding system requirements for physical or virtual appliances. For more information, see Which appliances do I need? and OT monitoring with virtual appliances.
Then, use any of the following procedures to continue:
