Common configuration mistakes
In some of Hyper-V infrastructures where I have worked to solve performance and stability issues, I have seen the same kind of misconfiguration several times. In this section, I have tried to describe the common configuration mistakes I have seen.
Design misjudged
The first common mistake I see in Hyper-V deployment is the underestimation of the design phase. A lot of projects where I was involved didn't start by studying the existing environment. How can you know the required numbers of CPUs, memory, and storage without inspecting the current infrastructure?
