What’s New in System Center 2012 SP1
Here are some general changes in VMM in the System Center 2012 SP1 release that you might need to consider:
-
The VMM Self-Service Portal is no longer supported in System Center 2012 SP1. Instead, we recommend that you use System Center 2012 SP1 - App Controller as the self-service portal solution. For more information about App Controller, see App Controller.
-
Self-service users can now use the VMM console instead of the VMM Self-Service Portal to perform tasks such as deploying virtual machines and services.
-
High availability with N_Port ID Virtualization (NPIV) is no longer supported. VMM is compatible with virtual (synthetic) fiber channels that are configured for virtual machines in Hyper-V.
The following tables summarize VMM enhancements and other changes in the System Center 2012 SP1 release.

|
Support for file shares that leverage the new 3.0 version of the Server Message Block (SMB) protocol that is introduced in Windows Server 2012. VMM in this release includes support for designating network file shares on Windows Server 2012 computers as the storage location for virtual machine files, such as configuration, virtual hard disk (.vhd/.vhdx) files and checkpoints. SMB 3.0 file shares provide the following benefits when they are used with VMM in this release:
You can create SMB 3.0 file shares on standalone Windows Server 2012 file servers and on clustered Windows Server 2012 file servers. If you use a standalone file server, you can designate an SMB 3.0 file share as the virtual machine storage location on a Windows Server 2012 Hyper-V host cluster. However, this is not a highly available solution. |
For more information about SMB 3.0 in Windows Server 2012, see Server Message Block Overview. For more information about how to create a highly available SMB 3.0 file share, see Scale-Out File Server for Application Data Overview, and steps 1 and 2 of the Deploy Scale-Out File Server scenario that is linked to from that topic. |

|
The new Windows Standards-Based Storage Management service replaces the Microsoft Storage Management Service in System Center 2012 – Virtual Machine Manager. The new service uses the Windows Storage Management application programming interface (API), a WMI-based programming interface that is included in Windows Server 2012. This new API enables you to discover storage by using multiple provider types.
In this release, VMM supports the following types of storage providers and arrays:
|
|||
|
Support for auto (dynamic) iSCSI target systems, such as the Dell EqualLogic PS Series. System Center 2012 – Virtual Machine Manager supports only static iSCSI target systems. |
|||
|
Support for thin provisioning of logical units through VMM. Your storage array must support thin provisioning. And thin provisioning must be enabled for a storage pool by your storage administrator. |
|||
|
Integration with third-party SANs and file-based storage on Windows Server 2012 File server. |

|
Support for using a virtual hard disk that is in the .vhdx format as the base operating system image. |
How to Discover Physical Computers and Deploy as Hyper-V Hosts in VMM |
|
Operating system deployment that utilizes deep discovery and Consistent Device Naming (CDN). CDN allows VMM to predictably assign network interface controllers (NICs) to the correct networks and teams. During the discovery process, you can run deep discovery to see more detailed information about the physical computer hardware before you deploy the operating system. In this release, deep discovery functionality is only partially enabled. You can view the physical network adapter information, information about the CPU, and the amount of memory. You can configure network options such as logical switches, and you can change the settings for the network adapter that VMM automatically designates as the management network adapter. |
How to Discover Physical Computers and Deploy as Hyper-V Hosts in VMM |
|
Support for physical network adapter configuration as follows:
|
|
|
Support for Host vNIC configuration. |
|
|

|
Support for the new version of the virtual hard disk format that is introduced in Windows Server 2012. This new format is referred to as VHDX. Compared to the older VHD format, VHDX has a much larger storage capacity of up to 64 TB. The VHDX format also provides data corruption protection during power failures. Additionally, it offers improved alignment of the virtual hard disk format to perform well on large-sector physical disks. Support for VHDX includes the following:

|
Storage migration, which allows for the migration of virtual machine storage. You can migrate storage in order to update the physical storage available in Hyper-V, or to mitigate bottlenecks in storage performance. Storage can be added to either a standalone computer or a Hyper-V cluster. Then, virtual machines can be moved to the new storage while they continue to run. |

Network Virtualization
VMM in this release provides support for the network virtualization capabilities that are available in Windows Server 2012.
Network virtualization provides the ability to run multiple virtual network infrastructures, potentially with overlapping IP addresses, on the same physical network. With network virtualization, each virtual network infrastructure operates as if it is the only one that is running on the shared network infrastructure. This enables two different business groups that are using VMM to use the same IP addressing scheme without conflict. In addition, network virtualization provides isolation so that only virtual machines on a specific virtual network infrastructure can communicate with each other.
Network virtualization in Windows Server 2012 is designed to remove the constraints of VLAN and hierarchical IP address assignment for virtual machine provisioning. This enables flexibility in virtual machine placement because the virtual machine can keep its IP address regardless of which host it is placed on. Placement is not limited by physical IP subnet hierarchies or VLAN configurations.
To virtualize the network in Windows Server 2012, each virtual machine is assigned two IP addresses as follows:
-
A customer address. This IP address is visible to the virtual machine and is used by customers to communicate with the virtual machine.
-
A provider address. This IP address is used by the Hyper-V computer that hosts the virtual machine. It is not visible to the virtual machine.
In this release, you can virtualize the IP address of a virtual machine by using Network Virtualization with Generic Routing Encapsulation (NVGRE). In NVGRE, all of the virtual machines packets are encapsulated with a new header before they are sent on the physical network. IP encapsulation offers better scalability because all of the virtual machines on a specific host can share the same provider IP address.
VMM creates the necessary IP address mappings for virtual machines to take advantage of the network virtualization capabilities in Windows Server 2012. To assign provider addresses, VMM uses an IP address pool that is associated with a logical network. To assign customer addresses, VMM uses an IP address pool that is associated with a virtual machine subnet that is, in turn, associated with a virtual machine network.
In this release, you can now assign customer addresses through DHCP or by using static IP addresses. When you create an IP address pool for a virtual machine subnet, the pool is automatically enabled to provision IP addresses by either mechanism. For DHCP to work correctly, the new DHCPv4 Server Switch Extension is required on all Windows Server 2012 Hyper-V hosts.
