Overview

When installed in a supported Linux virtual machine running on Hyper-V, the Linux Integration Components provide.

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 Multi-Processing (SMP) Support: Supported Linux distributions can use up to 4 virtual processors (VP) per virtual machine.

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.

====

New/updated from 3.1 release:

  • Synthetic Mouse Support: The virtualized mouse device is no longer bound to the VMConnect window, and can now be used with a RDP session.
  • Merged Device Drivers: We now present a single device driver for both IDE and SCSI devices (hv_storvsc).
  • Windows 8 Fix: The synthetic network device (hv_netvsc) can now be used with a Windows 8 host, eliminating the hang on boot that was previously seen.
  • SCVMM Fix: This release fixes the issue as described in KB2586286.
  • Improved Setup Experience: Users now only need to run install.sh (as root) to automatically detect the correct architecture and install the appropriate drivers.
