    Study Notes

    Deploying Virtual Machines

    • Virtual machines are the foundation of virtual infrastructure.
    • Deploying VMs involves:
      • Recognizing different types of virtual hardware
      • Creating, cloning, and managing VMs and templates
      • Modifying VMs
      • Updating templates
    • Virtual machines can be created via:
      • New Virtual Machine wizard (vSphere Client, VMware Host Client)
      • Templates or clones (vSphere Client)
      • OVF templates (vSphere Client, VMware Host Client)
    • Optimal method for provisioning VMs depends on:
      • Size and type of infrastructure
      • Goals to be achieved
    • The New Virtual Machine wizard can be used for single VM creation if existing VMs do not meet requirements.
    • A single VM can be used as a template for cloning other VMs.
    • Open Virtual Machine Format (OVF) templates are used to deploy VMs, virtual appliances, and vApps.
    • Virtual appliances are VMs with preinstalled operating systems and software.
    • OVF templates can be deployed from:
      • Local file systems
      • Removable media
      • Shared network drives
      • URLs
    • Hardware changes to VMs can be made while the VM is powered off or powered on.

    Hot-Pluggable Devices

    • Hot plug option allows adding resources to a running VM:
      • USB controllers
      • Ethernet adapters
      • Hard disk devices
    • CPUs and memory can also be added to VMs with supported guest operating systems.
    • Hot-plugging eliminates need for physical interaction with servers.
    • To remove hardware, the VM must be shut down, but reconfiguration can be done without entering the data center.

    CPU and Memory Hot-Plug

    • These features are supported only on guest operating systems with hot-pluggable functionality.
    • Features are deactivated by default.
    • Requirements for using hot-plug features:
      • VMware Tools must be installed
      • VM must use hardware version 11 or later
      • Guest operating system must support these features
      • Hot-plug features must be activated in CPU or Memory settings
    • If virtual NUMA is configured with virtual CPU hot-plug settings, the VM starts without virtual NUMA and uses UMA (Uniform Memory Access) instead.

    Dynamically Increasing Virtual Disk Size

    • The size of a virtual disk can be increased while the VM is powered on.
    • The disk must not have snapshots attached.
    • System tools may be required to make the new space usable.
    • Make appropriate changes to the VM.

    Converting a VM to a Template

    • Template updates can be performed by converting the template to a VM.
    • Changes can be made to the VM after powering it on.
    • For security, disconnect the VM from the network or place it on an isolated network during updates.
    • After updates, power off the VM and convert it back to a template.

    Deploying VMs from a Template

    • Requires providing information:
      • VM name
      • Inventory location
      • Host
      • Datastore
      • Guest operating system customization data

    Cloning Virtual Machines

    • Cloning creates an exact copy of the original VM.
    • Cloning is an alternative to deploying a VM from a template.
    • Source VM can be powered on or off.
    • Requires connection to vCenter
    • Local library is available for use in data centers that are objects to the local vCenter.
    • Published library is a local library available for subscription.
    • Content library tracks version changes using the vCenter database.
    • No option to use previous versions of content.
    • Subscribed library is configured to subscribe to a published library.
    • Administrator cannot directly change the contents of a subscribed library but can control synchronization to the subscribed library.

    Content Library Interface

    • Access the content library interface by selecting "Content Libraries" from the main menu.

    Creating a Local Content Library

    • Select the content library type, for example, Local content library.
    • Can mount an ISO file directly from a content library.
