Virtual machine design is just as important as physical hardware design and should be part of the physical design process. Correctly designing and configuring virtual machines with proper resource allocation will help increase consolidation in the virtual environment and ensure that a virtual machine has access to the resources that it requires to run the workloads efficiently.
A few questions that should be answered as part of the virtual machine design are as follows:
What resources will be assigned to individual virtual machines?
How will new virtual machines be deployed?
How will multiple virtual machines supporting an application be grouped based on dependencies?
How will virtual machines be placed on host resources to ensure the efficient use of resources and ensure availability?
How will physical servers be converted to virtual machines?
This chapter will cover right-sizing virtual machines to ensure that they have the resources they require without over-allocating resources...
