Yesterday Microsoft released the Linux Integration Services for Hyper-V Version 3.3. The Installation is pretty much the same as with version 3.2. You can check out my blog post about Install CentOS on Windows 8 Hyper-V for the installation.

Linux Integration Services Version 3.3 for Microsoft Hyper-V Features

When installed on a virtual machine that is running a supported Linux operating system, Linux Integration Services for Hyper-V provides the following functionality:

• Driver support: Linux Integration Services supports the network controller, and the IDE and SCSI storage controllers that were developed specifically for Hyper-V.
• Fastpath boot support for Hyper-V: Boot devices now take advantage of the block Virtualization Service Client (VSC) to provide enhanced performance.
• Timesync: The clock inside the virtual machine will remain synchronized with the clock on the virtualization server with the help of the pluggable time source device.
• Integrated shutdown: Virtual machines running Linux can be shut down from either Hyper-V Manager or System Center Virtual Machine Manager by using the “Shut Down” command.
• Symmetric multiprocessing (SMP) support: Supported Linux distributions can use up to 4 virtual processors per virtual machine. SMP support is not available for 32-bit Linux guest operating systems running on Windows Server 2008 Hyper-V or Microsoft Hyper-V Server 2008.
• Heartbeat: Allows the virtualization server to detect whether the virtual machine is running and responsive.
• KVP (Key-Value Pair) Exchange: Information about the running Linux virtual machine can be obtained by using the Key-Value Pair Exchange functionality on the Windows Server 2008 virtualization server.
• Integrated mouse support: The cursor is no longer bound to the VMConnect window when used with the Linux Graphical user interface.

Michel Lüscher from Microsoft Switzerland made a blog post back in April 2010 about how you install a Linux Guest system with the Integration Services in der Version 2.1
