What’s New in Hyper-V 2016

With the release of Windows Server 2016 a slew of new and exciting features have been added to Hyper-V.  Plus some features have been updated.  Below are some that I consider exciting and extremely helpful.

Hot add network card and memory

In Windows 2016, you can add or remove a network card to a VM as well as adjust the amount of memory to a VM, even if it is not set to dynamic memory, all without having to shut down the VM.

  • NIC card add or delete must be Generation 2 VM running Windows or Linux
  • Hot memory adds for Generation 1 or 2 VMs running Windows 10 or Server 2016

Rolling Hyper-V cluster upgrade

Now updating a Hyper-V cluster to 2016 is easier. You can add a node running Hyper-V 2016 to any cluster that is 2012 R2. As a result, you can update the cluster without downtime and exporting and importing virtual machines. The cluster will run at 2012 R2 level until all nodes are at 2016.

  • Manage the cluster, Hyper-V, and virtual machines from a node running Windows Server 2016 or Windows 10.
  • You can move virtual machines between all of the nodes in the Hyper-V cluster regardless of node OS.
  • To use any of the new Hyper-V features, all nodes must run Windows Server 2016 and the cluster functional level must be updated. PowerShell command: Update-ClusterFunctionalLevel
  • The virtual machine configuration version for existing virtual machines isn’t upgraded. You can upgrade the configuration version only after you upgrade the cluster functional level.

Nested virtualization

Now you can use a virtual machine as a virtualization host. This feature is best in a test or development environment. You’ll need:

  • At least 4 GB RAM available for the virtualized Hyper-V host.
  • To run at least Windows Server 2016 or Windows 10 build 10565 on both the physical Hyper-V host and the virtualized host. Running the same build in both the physical and virtualized environments generally improves performance.
  • A processor with Intel VT-x (nested virtualization is available only for Intel processors at this time).

These are just a few of the new and improved features that are found in Hyper-V 2016. Microsoft is making it easier for companies to upgrade their hosts and clusters, so that you can take advantage of all that Windows Server and Hyper-V 2016 has to offer.
