Learning VMware vSphere

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

Upgrading Virtual Machines


Once the vCenter Server and the ESXi hosts have been upgraded, the virtual machines may be upgrade so that they can use the new features that the release brings.

VMware Tools

VMware Tools should be upgraded prior to upgrading the virtual hardware version so that the drivers for any new virtual hardware are available. This can be done using a vSphere Update Manager predefined baseline or manually upgrading the virtual machines.

To manually upgrade a virtual machine's VMware Tools:

  1. Using the vSphere Web Client, right click a powered-on virtual machine.

  2. Select Guest OS | Upgrade VMware Tools:

  3. Log into the guest operating system of the virtual machine and follow any prompts that may appear.

Keep in mind that a restart may be required.

Virtual Hardware

Once VMware Tools has been upgraded then the virtual hardware version may be upgraded to the newest version. This process may be done on a single virtual machine (as demonstrated in this section) or may be done on multiple virtual...
