The first thing I recommend doing on your Linux VM server is running yum update. If you run ‘yum update’ after the installation you could see:
Kernel Panic after Yum Update – CentOS with Hyper-V Linux Integration Components, which would probably just add a few extra headaches.
Next, go to Microsoft, download and extract the Linux Integration Services package.
Next, install the Linux Integration Components:
Load the Linux Integration Components v2.1 iso into your VM.
When logged in as root, run:

During custom compiling of applications, sometimes you will see error messages like the following:
make: depmod: Command not found
That doesn’t necessarily mean your computer doesn’t have something installed, but it could mean the program just couldn’t find it.
Here is how to fix it:

I am runnning CentOS 5.5 in a VM on Hyper-V. I created a fresh installation. I then installed Hyper-V Linux Integration Components. After Installing them I ran yum update.
After running a “yum update”, and rebooting I received this error.
Unable to access resume device (/dev/VolGroup00/LogVol01)
mount: could not find filesystem '/dev/root'
setuproot: moving /dev failed: No such file or directory
setuproot: error mounting /proc: No such file or directory
setuproot: error mounting /sys: No such file or directory
switchroot: mount failed: No such file or directory
Kernel panic - not syncing: Attempted to kill init!
During the yum update process, it updated my kernel. Kernels that are installed after Hyper-V Linux Integration Components don’t always mesh well together. Here is how I fixed my issue.

Here is how I ran a copy of my Rackspace cloud server locally on my Hyper-V 2008 R2 Server. Why would you want to do that you ask? Well, there are many reasons. For example, I want to run all my applications in a test/staging environment before I push them live. I want to test all updates to my servers before I push them out live, testing large processes out without wasting money on CPU/bandwidth before running them live, etc. It is very nice to have a near exact copy of what you are running on rackspace cloud servers locally.
Part of the problem was I didn’t have any spare servers laying around that I could install linux and Xen on but I already had a Hyper-V server. This would allow me to run a linux VM, but how do you get a Rackspace cloud server backup running in Hyper-V.

If you are building PHP from source on a new server, you might run into few linux prerequisites before you can complete a ./configure. You might not need all of these, or you might need more depending on how much stuff you are including in your configure line. Here is how to fix a good majority of the issues you might run into on Centos 5.
