44 C H A P T E R 2 | Compute To create a new production checkpoint for a VM, turn on checkpoints for that VM, right-click the VM in Hyper-V Manager, and then, on the shortcut menu that appears, click Checkpoint, as shown in Figure 2-43. Figure 2-43: Menu option for creating a new production checkpoint for a VM Note If you turn off production checkpoints for a VM, the Checkpoint option will not appear in the shortcut menu for the VM.

Hot add and hot remove for network adapters and memory With Windows Server 2016 Technical Preview, you no longer need to plan for downtime to upgrade or downgrade memory on VMs hosted on Hyper-V. There is also no downtime when adding or removing a network card. Now, you can hot-add and hot-remove both network adapters and memory on the platform. This is a huge improvement that will ease the Hyper-V administrator's job. In a physical environment, installing additional RAM or adding a new network card is a time-consuming process that usually involves planning and downtime. With this new feature, you can accomplish everything with no downtime. Both service providers and enterprises can now scale up or scale down the memory of VMs in seconds by using either Hyper-V Manager or Windows PowerShell. Note Hot-add memory works for generation-1 and generation-2 guests running Windows Server 2016 Technical Preview. It does not work with Windows Server 2012 R2 or earlier.
