Linux Integration Services v2.1 Release Candidate Now Available

Microsoft announces the availability of the RC release of the Linux Integration Services v2.1. This new version includes new functionality, including timesync, integrated shutdown, and SMP support.

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

  • Driver support for synthetic devices: The Linux Integration Services support the synthetic network controller and the synthetic storage controller 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.
  • NEW: Timesync: The clock inside the virtual machine will now remain synchronized with the clock on the host.
  • NEW: Integrated Shutdown: Virtual machines running Linux can now be shut down from either the Hyper-V Manager or the VMConnect application using the “Shut Down” command.
  • NEW: Symmetric Multi-Processing (SMP) Support: Supported Linux distributions can now properly use up to 4 virtual processors (VP) per virtual machine.
  • NEW FOR RC: Heartbeat: Allows the host to detect whether the guest is running and responsive.
  • NEW FOR RC: Pluggable Time Source: A pluggable clock source module is included to provide a more accurate time source to the guest.

This version of the integration services for Hyper-V can be downloaded from here, and supports Novell SUSE Linux Enterprise Server 10 SP3, SUSE Linux Enterprise Server 11, and Red Hat Enterprise Linux 5.2 / 5.3 / 5.4 / 5.5.
