Windows Server 2008 R2 With Hyper-V Features
The key enhancements of Windows Server 2008 R2 with Hyper-V as
compared to Windows Server 2008 Hyper-V are:
• Live migration
• Dynamic virtual machine storage
• Enhanced processor support
• Enhanced networking support
From Windows Server 2008 R2 SP1 onwards, there are two additional
enhancements:
• Dynamic Memory—Allows the memory on a host machine to be pooled
and dynamically distributed to virtual machines as necessary. Based on
current workloads on a virtual machine, memory is dynamically added or
removed. Dynamic memory allocation is done without service interruption.
• RemoteFX—Introduces a new set of remote user experience capabilities
that enable a media-rich user environment for virtual desktops,
session-based desktops, and remote applications. RemoteFX enables a rich
desktop experience for virtual machine users through a 3D adapter and
USB redirection. The 3D scenarios in virtual desktops provide a virtualized
graphics processing unit (GPU) within the virtual machine. RemoteFX
provides intelligent capture and compression that adapts for the best user
experience in both virtual and session-based desktops.
