Installing the ISO Image for Photon OS 3.0

After you have downloaded the latest Photon OS ISO image into a folder of your choice, open VMware Fusion.

  1. Start the Installation Process

    From the File menu, choose New.


    From the Select the Installation Method dialog, select Install from disc or image, and then choose Continue.

    Installation method

  2. Select the ISO Image

    ISO image

  3. Select the Operating System

    On the Choose Operating System dialog, select Linux in the left-hand column and VMware Photon 64-bit in the right-hand column.

    Operating system

    Choose Continue.

  4. Select the Virtual Disk (Optional)

    If you are using a Fusion version that is older than Fusion 8, you might see the following dialog.

    Virtual disk

    If you see this dialog, unless you're installing into an existing machine, choose Create a new virtual disk from the Choose a Virtual Disk dialog, and then choose Continue.

    Note: Fusion v8 and later automatically defaults to creating a new 8GB disk and formats it automatically. If you want to use an existing disk, or if you want to pre-allocate all 8GB, go into VM Settings, choose Add Device, and choose either New Hard Disk or Existing Hard Disk. Expand Advanced options and configure whether you want to pre-allocate disk space (disabled by default) or split into multiple files (enabled by default).

  5. Configure VM Settings

    Important: Before you finish creating the Photon OS Virtual Machine, we strongly recommend that you customize the virtual machine and remove any unwanted devices that are not needed for a container run-time environment.

    VM settings

    To remove unnecessary devices, choose Customize Settings.

    First, choose a name for your Virtual Machine, along with the folder into which you create the Virtual Machine (or accept the default folder).

    Custom settings

    Choose Save. The virtual machine will be created. The Settings screen allows you to customize virtual hardware for the new virtual machine. If it does not automatically appear, open Settings from the Virtual Machine menu bar.


    You can remove (recommended) the following components that are not used by Photon OS:

    • Select Display and ensure that the Accelerate 3D Graphics option is unchecked (it should be unchecked, by default). Select Show All to return to the VM Settings.
    • Select CD/DVD (IDE) and ensure that the Connect CD/DVD Drive box is checked (it should be checked by default). Select Show All to return to the VM Settings.
    • Select Sound Card, un-check the Connect Sound Card Option, and click Remove Sound Card. Choose Remove to confirm your action. Select Show All to return to the VM Settings.
    • Select USB & Bluetooth and uncheck the Share Bluetooth devices with Linux setting. Select Show All to return to the VM Settings.
    • Select Printer and press the Remove Printer Port button in the bottom left hand corner. Choose Remove to confirm your action. Select Show All to return to the VM Settings.
    • Select Camera and press the Remove Camera button in the bottom left hand corner. Choose Remove to confirm your action. Select Show All to return to the VM Settings.
    • Select Advanced and ensure that the Pass Power Status to VM option is unchecked (it should be unchecked, by default). Select Show All, but do not close the VM Settings window.

      By default, Photon OS is configured with a disk size of 8GB. However, Photon OS uses only the portion of disk space it needs, usually much less that the entire disk size. If you want to pre-allocate the entire disk size (reserving it entirely for Photon OS instead), select Hard Disk, expand Advanced options, and check Pre-allocate disk space (by default, it is unchecked). Select Show All to return to the VM Settings.

  6. Configure a Secure Boot (Optional)

    Note: If you want to configure a secure boot for the Photon OS VM you created, edit its .vmx file and add the following line:

    firmware = "efi"

    The EFI boot ensures that the ISO content is signed by VMware and that the entire stack is secure.

    After you have made the customizations you want, close the Virtual Machine Settings window. You are now ready to boot and begin the installation process.

  7. Power On the VM

    Return to the Fusion main menu, select the Photon OS Virtual Machine, and click Start Up (you can also choose Start Up from the Virtual Machine menu).

    Fusion powers on the host and starts the installation. Within a few seconds, Fusion displays the Photon OS installer boot menu.

    Photon OS installer

    Press the Enter key on your keyboard to start installing.


    Read the License Agreement and press the Enter key to accept.

  8. Configure the Partition

    The Installer will detect one disk, which should be the 8GB volume configured as part of the virtual machine creation.


    Choose Auto to have the installer automatically allocate the partition, or choose Custom if you want to configure individual partitions, and then press the Enter key.

    Note: If you choose Custom, the installer displays the following screen.

    Custom partition

    For each custom partition, choose Create New and specify the following information:

    New partition

    Size - Preallocated size of this partition, in MB.

    Type - One of the following options:

    • ext3 - ext3 file system
    • ext4 - ext4 file system
    • swap - swap partition

      Mountpoint - Mount point for this partition.

      Choose OK and press the Enter key. When you are done defining custom partitions, choose Next and press the Enter key.

      The installer prompts you to confirm that you want to erase the entire disk.

      Disk erase

      Choose Yes and press the Enter key to accept and proceed with the installation.

  9. Select an Installation Option

    After partitioning, the installer prompts you to select one of three installation options:

    Installation options

    Each install option provides a different run-time environment. Select the option that best meets your requirements.

    Option Description
    Photon Minimal Photon Minimum is a very lightweight version of the container host runtime that is best suited for container management and hosting. There is sufficient packaging and functionality to allow most common operations around modifying existing containers, as well as being a highly performant and full-featured runtime.

    Photon Full Photon Full includes several additional packages to enhance the authoring and packaging of containerized applications and/or system customization. For simply running containers, Photon Full will be overkill. Use Photon Full for developing and packaging the application that will be run as a container, as well as authoring the container, itself. For testing and validation purposes, Photon Full will include all components necessary to run containers.
    Photon OSTree Server This installation profile will create the server instance that will host the filesystem tree and managed definitions for rpm-ostree managed hosts created with the "Photon OSTree Host" installation profile. Most environments should need only one Photon OSTree Server instance to manage the state of the Photon OSTree Hosts. Use Photon OSTree Server when you are establishing a new repository and management node for Photon OS hosts.

    Note: The option you choose determines the disk and memory resources required for your installation.

    Select the option you want and press the Enter key.

  10. The Network Configuration screen appears, select one of the four options to configure your network. Network Sonfiguration

    1. Choose Configure network automatically and select Next to configure the network automatically.
    2. To configure network automatically with the DHCP hostname, select Configure network automatically with a DHCP hostname and select Next. Enter the DHCP Hostname and select Next. ../images/DHCP_hostname_for_your_system.png
    3. To configure the network manually, select Configure Network manually. In the window that appears, enter the IP Address, Netmask, Gateway and Nameserver and select OK. ../images/Configure_Network_Manually.png

    4. If your network interface is directly connected to the VLAN trunk port, choose YES on the Configure the network screen. Enter the VLAN ID and select Next. Configure the network.

  11. Select the Linux Kernel

    The installer prompts you to select the Linux kernel to install:

    Linux kernel

    • Hypervisor optimized means that any components that are not needed for running under a VMware hypervisor have been removed for faster boot times.
    • Generic means that all components are included.
  12. Specify the Hostname

    The installer prompts you for a hostname and suggest a randomly generated, unique hostname that you can change if you want.


    Press the Enter key.

  13. Specify the System root Password

    Note: Photon OS will not permit commonly used dictionary words to be set as a root password.

    The installer prompts you to enter the system root password. Type the password, and then press the Enter key.


    Confirm the root password by typing it a second time.

    Password confirmation

    Press the Enter key. The installer proceeds to install the software. Installation times will vary based on the system hardware and installation options you selected. Most installations complete in less than one minute.

    Once finished, the installer displays a confirmation message (which includes how long it took to install Photon OS) and prompts you to press a key on your keyboard to boot the new VM.


  14. Reboot the VM and Log In

    Press any key on the keyboard and the virtual machine will reboot into Photon OS.


    As the initial boot process begins, the installer displays the Photon splash screen, and then a login prompt.

    At the login prompt, enter root as the username and provide the password chosen during the installation.


You can now use your container runtime environment and deploy a containerized application.
