1. Each VM has its own MAC address just like the physical server running Hyper-V does. This is a property of the VM's virtual network card (just like a physical network card). The External Virtual Switch that was created (you connect your VMs to it to allow them off the server) is just like any physical switch - it routes using MAC addresses.
2. I'm relatively new to Hyper-V and virtualization. What I would like to know, is the best way to create a Mac OS X VM running in Windows Hyper-V host. I'm currently using a Windows 10 based desktop running Hyper-V to create a test lab. I'd like to run a Mac OS X VM in Hyper-V in my test lab.
3. Get-VMNetworkAdapter -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. Get-VM Get-VMNetworkAdapter ft VMName, MacAddress.
4. Upon doing so, you will see the VM's settings window, which displays all of the VM's virtual hardware. Expand the 'Network Adapter' container and click on the 'Advanced Features' container. This will display the option to assign a static MAC address, as shown in Figure A. Hyper-V allows you to assign a static MAC address to a virtual network adapter.

In most network deployments, generated MAC addresses are a good approach. However, you might need to set a static MAC address for a virtual machine adapter with unique value.

Hyper-v Static Mac Address

The following cases show when you might set a static MAC address:

• Virtual machine adapters on different physical hosts share the same subnet and are assigned the same MAC address, causing a conflict.
• Ensure that a virtual machine adapter always has the same MAC address.

Differences between Hyper-V on Windows and Hyper-V on Windows Server. There are some features that work differently in Hyper-V on Windows than they do in Hyper-V running on Windows Server. Hyper-V features only available on Windows Server: Live migration of virtual machines from one host to another; Hyper-V Replica; Virtual Fiber Channel; SR.

By default, VMware uses the Organizationally Unique Identifier (OUI) 00:50:56 for manually generated addresses, but all unique manually generated addresses are supported.

Important

This version of Virtual Machine Manager (VMM) has reached the end of support, we recommend you to upgrade to VMM 2019.

This article provides information about System Center - Virtual Machine Manager (VMM) default MAC addresses, and describes how to create and manage a custom MAC address pool.

VMM uses static MAC address pools to automatically generate and assign MAC address to VMs. This article describes default MAC address pools in the VMM fabric and explains how to create custom pools.

Default MAC address pool settings:

Hyper-v Mac Address Dynamic Or Static

Before you start

Before you create a custom MAC pool note that:

• If you want to divide one of the default pools into smaller custom pools, you must first delete the default MAC address pool or the default VMware MAC address pool. You must delete the default pool to avoid duplicate MAC address assignments.
• The first three octets of the beginning and ending MAC address must be the same.
• You must enter a valid hexadecimal values between 00 and FF.
• The ranges that you specify cannot overlap.
• The address range must not have the multi-cast bit set to 1. For example, you cannot use addresses that start with X1, X3, X5, X7, X9, XB, XD, or XF, where X is any value.
• To avoid conflicts with addresses reserved by Microsoft, VMware, and Citrix, do not use the following prefixes:
  • Reserved for Microsoft: 00:03:FF; 00:0D:3A; 00:12:5A; 00:15:5D; 00:17:FA; 00:50:F2; 00:1D:D8 (except for the 00:1D:D8:B7:1C:00 – 00:1D:D8:F4:1F:FF range that is reserved for VMM)
  • Reserved for VMware: 00:05:69; 00:0C:29; 00:1C:14; 00:50:56 (except for the 00:50:56:00:00:00 – 00:50:56:3F:FF:FF range that is the reserved as the default VMware static range)

Create a custom pool

Hyper-v Set Static Mac Address

1. Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources > Create > Create MAC Pool.
2. In Create MAC Address Pool Wizard > Name and Host Group specify a name and description. In Host Group select the host groups that should use the pool.
3. In MAC Address Range specify the start and end addresses.
4. In Summary review the settings and click Finish. When the job shows as Completed verify pool in MAC Pools.

Release IP addresses

In some circumstances you might want to remove addresses from the MAC pool. For example if a host that was assigned an IP address during bare metal deployment is removed from VMM management, or if a VM goes into a missing state because it was removed outside VMM.

1. Click Fabric > Networking > MAC Address Pools > Home > Show > Fabric Resources.
2. In MAC Pools click the pool you want to modify > Properties.
3. In Inactive addresses select the addresses you want to release.
