Overview of this book

Computer virtualization is a method to enable the running of multiple application workloads on a machine to achieve efficient utilization and reduce the number of physical machines in a data center. This has now become the foundation of many modern day data centers. What began as a technology to virtualize x86 architecture has now grown beyond the limits of a server’s hardware and into the realm of storage and network virtualization. VMware is currently the market leader in developing data center virtualization solutions. This book goes into the details of designing and implementing VMware solutions that form the foundation of a VMware infrastructure. The book begins by introducing you to the concepts of server virtualization followed by the architecture of VMware’s hypervisor – ESXi and then by its installation and configuration. You then learn what is required to manage a vSphere environment and configure advanced management capabilities of vCenter. Next you are taken through topics on vSphere Networking, Storage, ESXi Clustering, Resource Management and Virtual Machine Management. You will then be introduced to SSL Certificate Management and its use in a vSphere environment. Finally, you will learn about the lifecycle management of a vSphere environment by effectively monitoring, patching and upgrading vSphere components using Update Manager. By the end of the book, you will know how to use VMware’s vSphere suite of components to lay the foundation of a modern day virtual infrastructure.

Preface

Virtual machine settings


An administrator can modify many advanced configurations of a virtual machine. These advanced configurations will affect the virtual machine's functionality, compatibility, and performance.

To modify the settings of a virtual machine, simply right click the virtual machine and select Edit Settings. This is shown in the following screenshot:

This action will open the virtual machine settings dialog:

From here, an administrator can modify the settings as required.

Enabling CPU Hot-Plug/Memory Hot-Add

Enabling Hot-Plug and/or Hot-Add allows you to add more CPU or memory resources, respectively, while the virtual machine is powered on.

Virtual machines do not support Hot-Add (adding memory) and Hot-Plug by default. This capability will need to be enabled on a per virtual machine basis in order to utilize it. The virtual hardware version needs to be 7 or greater, so an upgrade may be necessary. Not all guest operating systems support this functionality; make sure to verify...
