Hyper-V R2: MAC Address Management

  • Article

Hyper-V has always allowed you to configure virtual network adapters where the MAC address was generated dynamically.  These dynamic MAC address are selected from a random pool of MAC addresses.  With Windows Server 2008 R2 we have added a new section to the Virtual Network Manager that allows you to configure the range of MAC addresses that Hyper-V will use for dynamic MAC address generation:

 NewNetworkSettings2

This is very handy if you need to ensure that multiple physical servers in your environment are not using overlapping MAC address ranges.

Cheers,
Ben

    It would be great if this page showed the name of the WMI class to use to remotely reconfigure the range, to make it easy for people to remotely configure the ranges on several machines.

    Doug Gale - You want the MinimumMacAddress and MaximumMacAddress properties on the Msvm_VirtualSystemManagementServiceSettingData class.  Details here: msdn.microsoft.com/.../cc136941(v=VS.85).aspx Cheers, Ben
