SCVMM 2008 R2

VMM 2008 R2 supports the following new features of Windows Server 2008 R2:

1. Live migration between Windows Server 2008 R2 clustered hosts.
2. Network optimization detection during virtual machine placement. VMM 2008 R2 supports both Virtual Machine Queue (VMQ) and TCP Chimney, which are Windows Server 2008 R2 features that improve network performance for virtual machines.
3. Network adapters that support the VMQ feature are able to create a unique network queue for each virtual network adapter and then connect that queue directly to the virtual machine’s memory. This connection routes packets directly from the hypervisor to the virtual machine, bypassing much of the processing in the virtualization stack.
4. Network adapters that support the TCP Chimney feature are able to offload the processing of network traffic from the networking stack. Both of these features increase network performance and reduce CPU utilization.
5. Hot addition and removal of virtual hard disks (VHDs). In Windows Server 2008 R2, Hyper-V allows users to add and remove VHDs from a virtual machine while it is running.
