Course Introduction
Introduction to vSphere and the Software Defined Data Center
As a vSphere administrator, you must be familiar with the components on which vSphere is based. You must also understand the following concepts: Virtualization, the role of the ESXi hypervisor in virtualization and virtual machines Fundamental vSphere components and the use of vSphere in the software-defined data center Use of vSphere clients to administer and manage vSphere environments

Introduction to Containers
vCenter Server
vCenter Server helps you centrally manage multiple ESXi hosts and their virtual machines. If you do not properly deploy, configure, and manage vCenter Server Appliance, your environment might experience reduced administrative efficiency or ESXi host and virtual machine downtime.

Configuring and Managing Virtual Networks
When you configure ESXi networking properly, virtual machines can communicate with other virtual, and physical, machines. In this way, remote host management and IP-based storage operate effectively.

Configuring Standard Switch Policies
Configuring and Managing Virtual Storage
Understanding the available storage options helps you set up your storage according to your cost, performance, and manageability requirements. You can use shared storage for disaster recovery, high availability, and moving virtual machines between hosts.

Virtual Machine Management
Virtual machines are the foundation of your virtual infrastructure. Managing VMs effectively requires skills in creating templates and clones, modifying VMs, migrating VMs, taking snapshots, and protecting the VMs through replication and backups.

Resource Management and Monitoring
Although the VMkernel works proactively to avoid resource contention, maximizing performance requires both analysis and ongoing monitoring. Developing skills in resource management, you can dynamically reallocate resources so that you can use available capacity more efficiently.

vSphere Clusters
Most organizations rely on computer-based services like email, databases, and web-based applications. The failure of any of these services can mean lost productivity and revenue. By understanding and using vSphere HA, you can configure highly available, computer-based services, which are important for an organization to remain competitive in contemporary business environments. And by developing skills in using vSphere DRS, you can improve service levels by guaranteeing appropriate resources to virtual machines.

vSphere Lifecycle Management
Managing the life cycle of vSphere involves keeping vCenter Server and ESXi hosts up to date and integrated with other VMware and third-party solutions. To achieve these goals, you must understand how to use the new features provided by vSphere Lifecycle Manager, namely, clusterlevel management of ESXi hosts and the vCenter Server Update Planner.

About Lesson

Modifying Virtual Machines

Learner Objectives

After completing this lesson, you should be able to meet the following objectives:

  • Describe virtual machine settings and options
  • Add a hot-pluggable device
  • Dynamically increase the size of a virtual disk

Modifying Virtual Machine Settings

Modifying Virtual Machines

 

You can modify a VM’s configuration by editing the VM’s settings:

  • Add virtual hardware:
    • You can add some hardware while the VM is powered on.
  • Remove virtual hardware:
    • You can remove some hardware only when the VM is powered off.
  • Set VM options.
  • Control a VM’s CPU and memory resources.

Hot-Pluggable Devices

Modifying Virtual Machines

With the hot plug option, you can add resources to a running VM. Examples of hot-pluggable devices:

  • USB controllers
  • Ethernet adapters
  • Hard disk devices

With supported guest operating systems, you can also add CPU and memory while the VM is powered on.

Dynamically Increasing Virtual Disk Size

You can increase the size of a virtual disk that belongs to a powered-on VM. Modifying Virtual Machines

Inflating Thin-Provisioned Disks

 

Thin-provisioned virtual disks can be converted to a thick, eager-zeroed format. To inflate a thin-provisioned disk:

  • The VM must be powered off.
  • Right-click the VM’s file with the .vmdk extension and select Inflate.

Or you can use vSphere Storage vMotion and select a thick-provisioned disk as the destination.

VM Options: General Settings

Modifying Virtual Machines

You can use the VM Options tab to modify properties such as the display name for the VM and the type of guest operating system that is installed.

VM Options: VMware Tools Settings

You can use the VMware Tools controls to customize the power buttons on the VM.

VM Options: VM Boot Settings

Occasionally, you might need to set the VM boot options. Modifying Virtual Machines

Removing VMs

You can remove a VM in the following ways:

  • Remove from the inventory:
    • —The VM is unregistered from the ESXi host and vCenter Server.
    • —The VM’s files remain on the disk.
    • —The VM can later be registered (added) to the inventory.
  • Delete from disk:
    • —All VM files are permanently deleted from the datastore.
    • —The VM is unregistered from the ESXi host and vCenter Server.

Review of Learner Objectives
