product keys for each virtual machine. When using AVMA, virtual machines get bound to
the licensed Hyper-V server as soon as the virtual machine starts.
Network Isolation One nice feature of using Microsoft Hyper-V network virtualiza-
tion is the ability of Hyper-V to keep virtual networks isolated from the physical network
infrastructure of the hosted system. Because administrators can set up Hyper-V software-
defined virtualization policies, you are no longer limited by the IP address assignment or
VLAN isolation requirements of the physical network. Hyper-V allows for built-in network
isolation to keep the virtual network separated from the virtual network.
Dynamic Memory Dynamic Memory is a feature of Hyper-V that allows it to balance
memory automatically among running virtual machines. Dynamic Memory allows
Hyper-V to adjust the amount of memory available to the virtual machines in response
to the needs of the virtual machines. It is currently available for Hyper-V in Windows
Server 2012 R2.
