How-To: Installing Hyper-V Intergration Tool for Centos 5.6

1.   Download Linux Integration Services 2.1 for Windows Server 2008 Hyper-V R2 at http://www.microsoft.com/downloads/en/details.aspx?FamilyID=eee39325-898b-4522-9b4c-f4b5b9b64551
2.       Extract the download file.
3.       Mount the "LinuxIC v21.iso" to the target Centos machine
4.       Start the Centos VM
5.       At the console copy the components into the Centos VM by executing the below commands as root:
#mkdir /mnt/cdrom
#mount /dev/cdrom /mnt/cdrom
#mkdir /opt/linux_ic_v21_rtm
#cp -R /mnt/cdrom/* /opt/linux_ic_v21_rtm
6.       Navigate to the directory where the components copied
           #cd /opt/linux_ic_v21_rtm
7.       Install the components using "make" command
           #make
           #make install
Below screenshot shows when the command executed successfully

8.      Shutdown the VM
9.      Change the network emulate to synthetic network adapter if you have not use synthetic network adapter
10.  Check all integration services


11.  Start the VM. This time the network interface name will change to SETH0 instead of ETH0

If you have issue similar to error "unable to find /usr/kernels/2.6.18-238.9.1.e15_x86_64", you have to check the symlink for the build located at "/lib/modules/kernel/build". make sure it is not broken.

Removing "Update Failed" VMs from the VMM Administrator Console

Recently getting annoyed by the increasing number of VMs with status "Update
Failed". The last thing I remember that this happened after the one of my
Hyper-V host crashed, and ended up 2 identical VMs appear after the quick
migration took place.

Found this blog
http://blogs.technet.com/m2/archive/2010/04/16/removing-missing-vms-from-the-vmm-administrator-console.aspx
and below are my summary of the steps :

1. Close VMM Administrator Console
2. Stop "Virtual Machine Manager" service.
3. Backup the VMM database (optional)
4. Download and install "Microsoft SQL Server Management Studio Express"
from
http://www.microsoft.com/downloads/en/details.aspx?FamilyID=c243a5ae-4bd1-4e3d-94b8-5a0f62bf7796.
5. Launch "Microsoft SQL Server Management Studio Express", select VMM
database and execute script below.
6. Start the "Virtual Machine Manager" service.
7. The VMs with "Update Failed" should have gone by now.

COMMIT TRANSACTION T1
===========End Script===========

The above method does not work for me all time. In case you have the same
issue after the steps above are performed, you may try to remove host
cluster from the VMM.


This is my last resource and it always works for me ☺
