Resource Management and Monitoring VMware vCenter Server High Availability Configure and Manage Virtual Networks Scalability Configure and Manage Virtual Storage Patch Management Managing Virtual Machines Installing vSphere Components VMware vSphere: Install, Configure, Manage – Revision A 7-2 © 2011 VMware Inc All rights reserved Importance You must perform many cumbersome tasks when using physical machines For example, you must move server storage from one storage array to another, deploy servers with the same configuration, and add resources dynamically To address these issues and more, VMware vSphere® provides methods for you to add memory and expand virtual machine disk drives The ability to clone and deploy virtual machines from a template enables you to capture the state of a problematic virtual machine or deploy a virtual machine from a pre-configured standard Also, vSphere gives you the ability to migrate virtual machines and virtual machine disks from one VMware® ESXi™ host to another while the virtual machines are running VMware vSphere: Install, Configure, Manage – Revision A 7-3 © 2011 VMware Inc All rights reserved Module Lessons Lesson 1: Creating Templates and Clones Lesson 2: Modifying Virtual Machines Lesson 3: Migrating Virtual Machines Lesson 4: Creating Virtual Machine Snapshots Lesson 5: Creating a vSphere vApp and Registering a Virtual Machine VMware vSphere: Install, Configure, Manage – Revision A 7-4 © 2011 VMware Inc All rights reserved Lesson 1: Creating Templates and Clones VMware vSphere: Install, Configure, Manage – Revision A 7-5 © 2011 VMware Inc All rights reserved Learner Objectives After this lesson, you should be able to the following: Create a template Deploy a virtual machine from a template Clone a virtual machine Allow guest operating system customization by VMware vCenter Server™ VMware vSphere: Install, Configure, Manage – Revision A 7-6 © 2011 VMware Inc All rights reserved Using a Template A template is a master copy of a virtual machine used to create and provision new virtual machines The template is an image that typically includes a guest operating system, a set of applications, and a specific virtual machine configuration VMware vSphere: Install, Configure, Manage – Revision A 7-7 © 2011 VMware Inc All rights reserved Creating a Template Clone the virtual machine to a template The virtual machine can either be powered on or powered off Convert the virtual machine to a template The virtual machine must be powered off Clone a template Select the template in inventory first VMware vSphere: Install, Configure, Manage – Revision A 7-8 © 2011 VMware Inc All rights reserved Viewing Templates Two ways to view templates: Use the VMs and Templates inventory view Use the Virtual Machines tab in the Hosts and Clusters inventory view VMware vSphere: Install, Configure, Manage – Revision A 7-9 © 2011 VMware Inc All rights reserved Deploying a Virtual Machine from Template To deploy a virtual machine, you must provide such information as the virtual machine name, inventory location, host, datastore, and guest operating system customization data VMware vSphere: Install, Configure, Manage – Revision A 7-10 © 2011 VMware Inc All rights reserved Managing Snapshots The Snapshot Manager lets you review all snapshots for the active virtual machine and act on them directly: Revert to (Go to) a snapshot Delete one or all snapshots Reverted from Security Patch 2.0 to Security Patch 1.0.1 VMware vSphere: Install, Configure, Manage – Revision A 7-53 © 2011 VMware Inc All

fails, try the following: • • • Clone the virtual machine to a datastore that has more space Relocate the disk(s) of other virtual machines with cold migration to another datastore Relocate templates VMware vSphere: Install, Configure, Manage – Revision A 7-58 © 2011 VMware Inc All rights reserved Review of Learner Objectives You should be able to the following: Take a snapshot of a virtual machine and manage multiple snapshots Delete virtual machine snapshots VMware vSphere: Install, Configure, Manage – Revision A 7-59 © 2011 VMware Inc All rights reserved Lesson 5: Creating a vApp and Registering a Virtual Machine VMware vSphere: Install, Configure, Manage – Revision A 7-60 © 2011 VMware Inc All rights reserved Learner Objectives After this lesson, you should be able to the following: Describe a vApp Build a vApp Manage virtual machines using vApp Remove a virtual machine from the vCenter Server inventory and completely from disk Manage virtual machine snapshots VMware vSphere: Install, Configure, Manage – Revision A 7-61 © 2011 VMware Inc All rights reserved Managing Virtual Machines with vSphere vApp (vApp) A vApp: Is a container for one or more virtual machines Can be used to package and manage related applications Is an object in the vCenter Server inventory VMware vSphere: Install, Configure, Manage – Revision A 7-62 © 2011 VMware Inc All rights reserved vApp Characteristics You can configure a vApp: CPU and memory allocation IP allocation policy Advanced settings You can also configure the virtual machine startup and shutdown order VMware vSphere: Install, Configure, Manage – Revision A 7-63 © 2011 VMware Inc All rights reserved Remove a Virtual Machine Two ways to remove a virtual machine: Remove a virtual machine from the inventory • • • Unregisters virtual machine The virtual machine’s files remain on disk The virtual machine can later be registered (re-added) to the inventory Delete a virtual machine from disk • The virtual machine is removed from the inventory, and its files are permanently deleted from disk VMware vSphere: Install, Configure, Manage – Revision A 7-64 © 2011 VMware Inc All rights reserved Lab 13 In this lab, you will perform several virtual machine management tasks Unregister a virtual machine in the vCenter Server inventory Register a virtual machine in the vCenter Server inventory Unregister and delete virtual machines from disk Take snapshots of a virtual machine Revert to a snapshot Delete an individual snapshot Use the Delete All function in Snapshot Manager VMware vSphere: Install, Configure, Manage – Revision A 7-65 © 2011 VMware Inc All rights reserved Review of Learner Objectives You should be able to the following: Describe a vApp Build a vApp Manage virtual machines using vApp Remove a virtual machine from the vCenter Server inventory and completely from disk Manage virtual machine snapshots VMware vSphere: Install, Configure, Manage – Revision A 7-66 © 2011 VMware Inc All rights reserved Key Points You can use several methods to create a virtual machine Choose the method that best fits your needs Deploying virtual machines from a template allows you to easily create many virtual machines vCenter Server provides useful features for provisioning virtual machines, such as templates and cloning VMware vSphere: Install, Configure, Manage – Revision A 7-67 © 2011 VMware Inc
