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

  • Driver support for synthetic devices: Linux Integration Services supports 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.
  • Timesync: The clock inside the virtual machine will remain synchronized with the clock on the host.
  • Integrated Shutdown: Virtual machines running Linux can be shut down from either Hyper-V Manager or System Center Virtual Machine Manager, using the “Shut Down” command.
  • Symmetric Multi-Processing (SMP) Support: Supported Linux distributions can use up to 4 virtual processors (VP) per virtual machine.

Download Linux Integration Components v2.1

a. Download Linux Integration Components v2.1 from Microsoft Download site.

b. Extract the .exe file into a temp folder. You will need only LinuxIC v21.iso file.

c. Place the LinuxIC v21.iso file into your VM host server where you can mount the ISO as a CDROM for your Centon Virtual Machine.

Installation :

You will need Development Tools installed to be able to compile the Integration Components. You could do that by running yum:

yum groupinstall “Development Tools”

NOTE: This command will try to use your network connection to download and if you used Synthetic Network Adapter for your Hyper-V machine you will not have internet connection. So make sure to install Development Tools during your Centos initial installation.

Now make sure you added LinuxIC v21.iso file to your Hyper-V CDROM as Image.

As the root user, mount the CD in the virtual machine by issuing the following commands at a shell prompt:

mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom

Copy Linux Integration Services to the virtual machine and unmount CDROM that no longer needed:

mkdir /opt/linux_ic_v21_rtm
cp –R /mnt/cdrom/* /opt/linux_ic_v21_rtm
umount /mnt/cdrom

As the root user, run the following command to compile and install the synthetic drivers:

cd /opt/linux_ic_v21_rtm/
make
make install

NOTE: If you’re using the x64 version of Centos, you have to perform an extra step.

Attach the Centos ISO that was used for installation in the virtual machine, and mount it:

mkdir /mnt/cdrom
mount /dev/cdrom /mnt/cdrom

Install the adjtimex RPM for more accurate time keeping in the virtual machine:

rpm –ivh /mnt/cdrom/Centos/adjtimex-1.20-2.1.x86_64.rpm

To verify that all subcomponents are running,, as the root user, issue the following command at a shell prompt:

/sbin/lsmod | grep vsc

Please remember when using Network Adapters on Hyper-V, NIC names would be changed from eth0 to seth0.
