Linux Integration Services Version v3.2 for Hyper-V now available

  • Comments 6

Yesterday we released a new version of the Linux Integration Services for Hyper-V.  You can download them directly from here:

Some key changes / new features to call out are:

  • Integrated mouse support
    Yay!  This means that you no longer need to install a separate package to get integrated mouse support, and will not have to worry about the mouse being captured by the virtual machine.
  • Updated network drivers that work with the Windows 8 Developer Preview builds
    I am happy to see this – as I am running this build of Windows *everywhere* at the moment
  • Fixes the issue with SCVMM compatibility
    The problem is documented here: – and should not be a problem anymore.

For more details, check out the link and read the documentation.

  • Great news! This will be nice for our CentOS machines. Two questions though - will Microsoft ever support Debian based distros? Do you know when/if the newer ICs will make it into the Linux kernel? I've used the kernel drivers in staging on Ubuntu VMs before, and they seem to work well, except that there is no mouse support. Also, the KVP capabilities would be nice.

  • Hi!

    I have IS v3.1 installed on my virtual centos 6.0. When I'm trying to update it to v3.2 using rpm, it says that there's newer version already installed. It works if I manually remove v3.1 before installing v3.2. Simple rpm update doesn't work. What is it?

  • I second Josh's questions.  Any idea?

  • @Alexey - I ended up just uninstalling the previous RPMs and then installed the new ones. No ill effects that I could see. Hope that helps!

  • After having complained about the previous release, I'm happy to praise 3.2 for its correct file naming, its smaller (!) ISO size, its mouse support (finally recognizing that Dr. Srinivasan's efforts to get hv_mouse into the kernel were not going to reach any real-world distro for a long time), and the thoughtful inclusion of (although you must cd to its path before running). My only remaining "suggestion for improvement" is the terse procedure on page 9 of the Read Me for configuring the synthetic NIC. The System/Administration/Network tools are not available without installing a bunch of packages that I rarely want to have inside my RHEL guests. I usually start with the "Minimal" kickstart and add a few specific packages from the "Base" group. As a result, I must manually create /etc/sysconfig/ifcfg-eth0 after running and I would surely appreciate it if future versions of would do it for me so that I won't have to customize the ISO like I have done for now.

  • Today, I have tried to use this component together with RHEL 6.2.

    The NIC eth0 was not found because of the well known "Dropping NETIF_F_SG since no checksum feature." emulation leak of this package.

    As far as I understand this is an indication the the device driver to the OS.

    My question now: Will the next version of "Linux Integration Services Version v3.x for Hyper-V" avoid this troubles - and how long will I have top wait?
