Linux Integration Services 3.1 for Hyper-V

Microsoft has released version 3.1. of the Linux Integration Services for Hyper-V. Linux Integration Services are a set of drivers that enable synthetic device support in supported Linux virtual machines under Hyper-V.

The supported operating systems for 3.1 are Red Hat Enterprise Linux (RHEL) 6.0 and 6.1 x86 and x64 (Up to 4 vCPU) and CentOS 6.0 x86 and x64 (Up to 4 vCPU), while SLES 10 SP3 and 11, and RHEL 5.2 / 5.3 / 5.4 / 5.5 still have support using Integration Services 2.1 for Hyper-V.

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.
