Accessing LAN Devices on the Hyper-V Host

In a virtualized environment, it's common to have multiple virtual machines (VMs) running on a single physical host. One of the key benefits of using Hyper-V is the ability to connect these VMs to the host's network, including LAN devices. This article will guide you through the process of setting up and accessing LAN devices from a Hyper-V host.

Prerequisites

For this example, we will be using the following setup:

• Host: Windows 11 Pro (192.168.1.10)
• Hyper-V: Ubuntu VM 1 (192.168.1.11, hosting web service)
• Hyper-V: Ubuntu VM 2 (192.168.1.12)

Step 1: Enable Virtual Switch

First, you need to create a virtual switch that connects your VMs to the host's network.

1. Open the Hyper-V Manager.
2. Right-click on the server name and select "Virtual Switch Manager".
3. Click on "New Virtual Network Switch" and choose "External".
4. Name the switch, select the appropriate network adapter, and click "OK".

Step 2: Connect VMs to the Virtual Switch

Next, connect your VMs to the newly created virtual switch.

1. Select a VM and click on "Settings".
2. Under the "Network Adapter" section, select the virtual switch you created.
3. Repeat this process for all VMs that need access to the LAN devices.

Step 3: Access LAN Devices

Now that your VMs are connected to the virtual switch, they should be able to access the LAN devices on the host network.

1. For Linux VMs, you can use the ping command to test connectivity. For example:

ping 192.168.1.10

2. For Windows VMs, open Command Prompt and type:

ping 192.168.1.10

Troubleshooting

If you're having trouble accessing the LAN devices, ensure that:

• The VMs are connected to the correct virtual switch.
• The firewall on the host and VMs is not blocking the necessary traffic.
• The IP addresses of the VMs and LAN devices are correct.
