In this article, we shall discuss the steps on how to run Hype-V on Windows 11 and Install Windows OS via PXE Boot. The Preboot Execution Environment (PXE) allows seamless access to the Windows Preinstallation Environment (WinPE) over the network. This enables efficient deployment and troubleshooting without requiring local installation media.

PXE is an industry standard created by Intel that provides pre-boot services within the devices firmware. It enables devices to download network boot programs to client computers.

Note: Remember to create your vSwitch before hand. You can also create this even after you have created your VM. But you will have to modify the VM to assign the switch via the VM settings.

MAC address Range for VMs

This section defines how to decide on a custom MAC address when you do not want to use the default (dynamic Mac Address) for Hyper-V VMs. This is also applicable to VMware. To learn more on how to set up MAC address pools in the VMM fabric

MAC pool name	Environment	Default range
Default MAC address pool	Hyper-V	00:1D:D8:B7:1C:00 – 00:1D:D8:F4:1F:FF
Default VMware MAC address pool	ESX/ESXi	00:50:56:00:00:00 – 00:50:56:3F:FF:FF

Since I am working on Hyper-V. I will manually create and assign a MAC address to my VM(s). This will be from the range of information provided in the table above.

For HyperV and VMware. The last 6 characters of the UUID of a virtual machine are indeed used to form the last three octets (24 bits) of the MAC address.

VMware generates MAC addresses using the 00:50:56 OUI range, which IEEE assigns to VMware. Similarly, Hyper-V uses a static range of MAC addresses assigned by Microsoft starting from 00:1D:D8 range as its organizationally unique identifier. The rest of the MAC address (last three octets) is generated pseudo-randomly or programmatically to ensure uniqueness within the virtual network.

Why Is having a Duplicate MAC Addresses on VMs a Problem?

Having the same MAC address on multiple virtual machines (VMs) in your environment can be problematic- This is because, it violates the principle of uniqueness that MAC addresses are designed to uphold. This can lead to several issues in your network as discussed below;

Network Communication Conflicts: Switches use MAC addresses to forward traffic. If two VMs share the same MAC address. The network switch cannot correctly maintain their MAC address tables, causing network traffic to be misrouted or broadcasted unnecessarily.

Duplicate MAC addresses can cause ARP table issues. This can lead to devices sending packets to the wrong destination. This is because, the Address Resolution Protocol (ARP) maps IP addresses to MAC addresses.

Security Risks: A malicious actor could exploit duplicate MAC addresses to intercept traffic, impersonate other devices on the network, and potentially violate compliance regulations that mandate unique device identifiers.

Connectivity Problems: Switches and routers may drop network packets or cause devices to lose connectivity entirely as they struggle to identify the correct machine when VMs have identical MAC addresses.

The list of issues is endless, so either let your VM host dynamically manage the VM’s MAC address. Because, VMware and Hyper-V automatically generate unique MAC addresses for VMs within a specific range. Or assign it correctly yourself ( ensure that each VM is assigned a unique address within the allowed range).

Note: Maintain a registry of manually assigned MAC addresses to prevent duplicate Mac Addresses.

Enable Hyper-V on Windows 11

Press Win + R, type optional features, and hit Enter. Alternatively, search for Control Panel, click on Programs and then “on Turn Windows Features on or off”.

Turn Windows features on or off — Hyper-V is built into Windows as an optional feature. There’s no Hyper-V download.

Please select, Check Hyper-V and expand Hyper-V and ensure Hyper-V Management Tools and Hyper-V Platform are selected as shown below. Note: You can also do this via PowerShell with the command below.

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V -All

Select Features — The Hyper-V Platform contains the actual virtualization infrastructure that enables your Windows 11 device to run multiple virtual machines. Without it, your system cannot perform the core virtualization functions, even if you have the management tools enabled.

As you can see, changes are being applied.

When prompted, please restart your PC to apply the needed changes.

Create Virtual Machine

Next, proceed to create a new VM. To do this, launch the Hyper-V Manager. In Hyper-V Manager, on the right-hand panel, click New > Virtual Machine.

You can skip the before you begin page or click on “Do not show this page again”.

Enter a descriptive name for the virtual machine and click on Next

Configure VM Generation

Please specify VM generation. Please take a look at the link above to learn about the differences between the two options. Generation 2 is recommended for newer operating systems (UEFI-based) that support secure boot and faster boot options.

Configure Networking

We have discussed extensively in our archive, please search through our blog post on how to create vSwitches via PowerShell and via the Hyper-V Manager.

Please select the vSwitch you have created or click on Next as shown below. Mind you, you will come back and modify your VM if you desire internet access.

Choose to Create a virtual hard disk and specify the size. I am Okay with the default size as shown below.

I will select install Operating System later as I will be using PXE Boot.

Review the VM summary and click on Finish.

Get-VMNetworkAdapter command on PowerShell

By using the following command from the Hyper-V host (locally or remotely) you can view the MAC address of the VM you specify.

Get-VMNetworkAdapter -VMName <vmname>

In addition, to view the MAC addresses of all VMs of a Hyper-V host, you can use the following command.

Get-VM | Get-VMNetworkAdapter | ft VMName, MacAddress
