I'm trying to create a fingerprint of servers using c#. It is important that the logic works for virtual servers so that the fingerprint does not change when the VM is migrated to another host.
I found this sample on codeplex: http://www.codeproject.com/Articles/28678/Generating-Unique-Key-Finger-Print-for-a-Computer This is using the following components to create the fingerprint: cpu, bios, motherboard, disk, video card and mac address. I would also use the computer name.
Now my question is: Which components are not changing after migrate the vm to another host? I think the cpu and the mac address are not changing.
