CentOS Added as Supported Guest Operating System Running on Hyper V


CentOS is a new family members on Linux distribution supported by Microsoft. The news is announce @ Microsoft TechEd North America 2011, Atlanta  Previously, Microsoft only support the following guest operating system

  • SUSE Linux Enterprise Server 10 with Service Pack 3 (x86 Edition or x64 Edition)
  • SUSE Linux Enterprise Server 11 (x86 Edition or x64 Edition)
  • Red Hat Enterprise Linux (RHEL) 5.2, 5.3 , 5.4 and 5.5 (x86 Edition or x64 Edition)

Therefore as usual, i have downloaded CentOS 5.6 from and deploy on my lab data center. The total size of the iso download is  4.58GB. Quite sometime, i did not perform linux installation. Let quickly review the setup on Hyper V platform.


I did a full graphical installation. In term of mouse movement, i can use the mouse to click here and there without Citrix Project Satori installation. Project Satori is the result of a collaboration agreement between XenSource and Microsoft. Meanwhile, Linux Integration 2.1 released by Microsoft do not have mouse support. Therefore to provides enlightened mouse driver, you need to download from

Then i try shutdown from Hyper V  Console but it did not work since the Integration Component is not install. To download Linux Integration v2.1, go to

Make sure entire Software Development package is installed on CentOS before you install the IC.

Here is part of the configuration on the CentOS to get the IC ver2.1 working:-

1. Use Hyper V manager snap in to mount the IC ISO.

2. Type the following command



3. Type reboot to restart the CentOS

Verification that i performed after IC ver2.1 install:-

a) Synthetic NIC available. Before install IC, i did not have NIC assign to CentOS.


b) Initiate Shutdown from Hyper V Manager Console. Now the CentOS was able to shutdown from the snap-in.


c) Time synchronization. Change time from parent Hyper V host will reflect to CentOS VM.


This is great. Hope you can explore further. Good Luck.
