I have a Hyper-V environment on Windows Server 2012 Datacenter. One of the Virtual Machine (VM) has a License Server. One of the license was generated due to the Mac address that the VM had at that moment. My VMs take the MAC addresses dynamically from the Hyper-V pool. I will change the Mac address configuration in only that VM from dynamic to static MAC address. I will put the MAC address that the VM had at that moment (the license file gives me the MAC at that moment) but I would like to exclude that MAC address from the Hyper-V MAC address pool to avoid conflicts. How can I exclude an specific MAC address from the Hyper-V pool?
