    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. To remove unnecessary devices, choose Customize hardware.

    Customize hardware

    Consider removing the following components, which are not used by Photon OS:

    • Select Sound Card, un-tick the Connect at power on option. Confirm your action and choose Close to return to the VM Settings by .
    • Select USB Controller and ensure that the Share Bluetooth devices with the virtual machine setting is unchecked (it should be unchecked, by default) and then choose Close.
    • Select Display and ensure that the Accelerate 3D Graphics option is unchecked (it should be unchecked, by default) and then choose Close.
    • At this stage we have now made all the necessary customizations and you are ready to select the Photon OS ISO image to boot and begin the installation process.
    • Choose Finish.

      In Workstation, choose Edit virtual machine settings, select CD/DVD (IDE), and verify that Connect at power on is selected.


  7. Configure a Secure Boot (Optional)

    Note: If you want to configure a secure boot for the Photon OS VM, in Workstation, choose Edit virtual machine settings, select Options, choose Advanced, and select Boot with EFI instead of BIOS.

    Boot with EFI

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

    Choose OK.

  9. 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:

    installation option

    Each installation option provides a different run-time environment, depending on 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.

  11. 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.

    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.

  12. Select the Linux Kernel

    Select a Linux kernel to install.


    • 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.

      Choose Next and press the Enter key.

  13. 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.

    The installer prompts you to confirm the root password by typing it a second time.

    Confirm password

    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.

  15. Reboot the VM and Log In

    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.

    confirmation message

    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.
