Microsoft has updated the Linux Integration Services (aka integration components or the Hyper-V enlightenments) from v3.1 to v.3.2 supporting Redhat Enterprise Linux (x86 and x64, 6.0 and 6.1) and CentOS 6.0 (x86 and x64).

I think no new features are listed.  My guess is that v3.2 includes a fix  or workaround for Key Value Pair exchange and SCVMM.  But that is a guess.  I’ll try to find out more.

You’ll continue to use Linux Integration Services 2.1 for SLES 10 and RHEL 5.

EDIT #1:

I did some comparisons between 3.1 and 3.2 text and noticed this is added in 3.2:

“Integrated Mouse Support: The cursor is no longer bound to the VMConnect window when used with the Linux Graphical User Interface”.

EDIT #2:

Thanks to Mike Sterling (Program Manager at Microsoft) for sharing the following info on new features in the V3.2 Integration Services:

  • 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.

  1. Linux. Phooey.


    • But it’s a deal breaker for many if it doesn’t have support.

  2. Have you noticed that both IC V 3.1 and 3.2 seem to kill the CDROM in Redhat 6.1? It has happened to me on two VMs. I am trying to get back into Unix/RedHat and can’t figure out how to get the cdrom back…

    • I’ve not had that problem. You might be able to log something via Connect.

      • Aidan, haven’t you mentioned this problem in the list of Hyper-V related patches couple posts below? (http://support.microsoft.com/kb/2600152/en-us?sd=rss&spid=14134). Or is this different issue?

        • I mentioned the issue with the V3.1 IC’s in that post. However, that was a workaround that disabled data exchange via disabling KVP. A hack rather than a fix. V3.2 fixes the actual issue.
