Do virtual machines bear the same MAC address as the host server?
In a Microsoft Hyper-V environment, each virtual machine is assigned a dynamic MAC address by default. This MAC address differs from that of the host server and normally differs from the MAC addresses assigned to other virtual machines. Hyper-V also gives you the option of assigning a static MAC address to each virtual network adapter within a virtual machine. A VMware ESX also gives you the option of using either static or dynamic MAC addresses on virtual machines.
