HyperV Internal Network: Unidentified Network Keeps Resetting after Windows 11 Upgrade

Hyper-V Internal Network: Unidentified Network Keeps Resetting Windows 11 Upgrade

Hyper-V is a popular virtualization technology developed by Microsoft. It allows users to create virtual machines (VMs) on a physical host to run multiple operating systems simultaneously. One common use case for Hyper-V is to enable file sharing access via SMB guest hosts.

Background

Recently, many users have upgraded their Windows 11 operating system to the latest version. However, they have encountered issues with the Hyper-V internal network, which keeps resetting, causing the Windows 11 upgrade to fail. This article aims to provide a detailed explanation of the issue and offer possible solutions.

Understanding the Hyper-V Internal Network

The Hyper-V internal network is a virtual network that allows VMs to communicate with each other and the host operating system. It is created using the Hyper-V virtual switch, which provides network connectivity to VMs. The Hyper-V internal network is isolated from the physical network, making it ideal for testing and development purposes.

Issue: Unidentified Network Keeps Resetting Windows 11 Upgrade

After upgrading to Windows 11, some users have reported that the Hyper-V internal network is resetting, causing the Windows 11 upgrade to fail. The issue is caused by an unidentified network that appears in the network connections list. The network connection is automatically assigned a new IP address, causing the Hyper-V internal network to lose its network configuration.

Solution

To resolve the issue, users can try the following steps:

1. Open the Hyper-V Manager and select the host operating system.
2. Click on the Virtual Switch Manager and create a new virtual switch.
3. Select the Internal network option and assign a name to the new virtual switch.
4. Configure the new virtual switch with a static IP address and subnet mask.
5. Connect the VMs to the new virtual switch.

Code Block Example

Here is an example of how to configure a static IP address for the Hyper-V internal network:
