I have installed Centos 5.5 on Hyper-V R2 machine and all worked well.
Then I installed integrated services and it did changes to kernel.
This article needs to be updated, but at least it directed me into right path:
then I installed "Perfect server"
yum update upgraded my kernel and it seems to change kernel.
after that I was not able to load server and was getting error:
Mounting root filesystem.
mount: could not find filesystem '/dev/root'
Setting up other filesystems.

I found this article:
The article above says how to fix this issue on Xen, but I'm running Hyper-V.
Can anyone help and give step by step guide like that but that fixes kernel on Hyper-V?
