SCVMM 2008 R2 SP1 is RTM
WOW – Finally SP1 for Windows 2008 R2 + SP1 for System Center Virtual Machine Manager (SCVMM) 2008 R2 goes hand in hand and we can start with deploying SP1 features in our production environments 
where SCVMM is use for managing your virtualization farm’s (Hyper-V/VMWare).
Microsoft has now RTM’d the SP1 for SCVMM 2008 R2 which offers now the capability to manage the new features from SP1 for Windows 2008 R2 Hyper-V (and of course Hyper-V 2008 R2) like Dynamic Memory and RemoteFX.
- Dynamic Memory: Windows Server 2008 R2 SP1 Hyper-V supports Dynamic Memory enabling customers to better utilize the memory resources of a Hyper-V host. VMM 2008 R2 SP1 allows administrators to create and deploy Virtual Machines onto Windows Server 2008 R2 SP1 Hyper-V hosts and will report on the memory currently in use for these VMs where Dynamic Memory is enabled. Using Dynamic Memory for supported VMs allows for more efficient utilization of memory, with consistent performance, and higher consolidation ratios.
- Microsoft RemoteFX: Windows Server 2008 R2 SP1 introduces a new set of end user experience enhancements with Microsoft RemoteFX. VMM 2008 R2 SP1 allows administrators to create and deploy Virtual Machines with RemoteFX enabled to qualified Windows Server 2008 R2 SP1 Hyper-V hosts. This enables a rich, local-like desktop environment over the network.
