Is there a white paper explaining why we we need less memory in Virtual Machine as compared to Physical Machine.
The problem here is my boss wants to know why it is so. It is very difficult for me to explain him this reason, he wants to see a white paper OR some article on the internet.
As a VM admin, I know we can add and remove the memory to a VM but it won't be that easy when we talk about Physical servers. I suggested him that we should follow a standard and if there is a business requirement we can increase/decrease is as needed. Now when the vendor comes in they give us specs for Physical server and not the virtual and there is always a argument that why should VM be having 6-8 GB of memory upfront. So to avoid all that arguments he needs some other proof.
Thanks
