Microsoft Hyper-V has plenty of features when you run it on a regular Hyper-V host, but there's a way to have more options with those features.
Running Hyper-V on a Windows Server 2012 R2 introduces even more options for the virtualization features you can use. These features are available from the Hyper-V Manager on Hyper-V host, but using these features through SCVMM 2012 R2 management product provides you the greater flexibility and usability. Here are some of the new features of Hyper-V R2, when used via SCVMM 2012 R2, that provide a rich experience.
Hyper-V 2012 R2 supports live cloning of virtual machines (VMs). VMs running on Hyper-V 2012 R2 can be cloned without any downtime. Although you can use the live cloning feature from Hyper-V Manager, SCVMM 2012 R2 offers you greater flexibility by allowing you to clone a VM from a remote Hyper-V host or from a VM that is already prepared and stored in the SCVMM library.
Windows Server 2012 R2 now supports creating a site-to-site network gateway, sometimes referred to as HNV or NVGRE gateway in a Hyper-V Network Virtualization environment. Although you can add a NVGRE gateway without using SCVMM, you would need to use a lot of PowerShell commands and managing these gateways is cumbersome. SCVMM R2 helps you deploy a NVGRE gateway without adding unwanted complexities. Another important factor with regards to adding an HNV gateway is that only SCVMM 2012 R2 supports adding a third-party gateway, such as nAppliance or F5. All you need to do is to add a network service through SCVMM 2012 R2 and deploy the gateway to Hyper-V hosts.
The VHDX sharing feature of Hyper-V 2012 R2 enables guest clustering. SCVMM 2012 R2 takes it another step and enables integration of the VHDX sharing feature in service templates which, in turn, enables the rapid deployment of VMs with clustering support on virtualization hosts.
