Creating Linux Virtual Machine Images

Procedure

1. Open VirtualBox.
   The VirtualBox Manager window opens.

   

2. Click New.
   The New Virtual Machine window opens. By default, Virtual Box opens in Expert Mode. If you are in Guided Mode instead, click Expert Mode.

   

3. Configure the Virtual machine name and operating system settings.
   • Type a permanent and unique VM Name for the virtual machine.
   • Specify the VM Folder to store the completed virtual machine.
   • Specify the ISO Image for the virtual machine.
   • For the OS, select Linux.
   • Select the OS Version based on your Linux OS:
     • For CentOS 7.8, RHEL 7.9, and RHEL 8.3, select Red Hat (64-bit)
     • For Ubuntu 20.04.6, select Ubuntu (64-bit)
4. Open the Specify virtual hardware section.

   

5. Specify the recommended memory size for your operating system.
   • CentOS 7.8: 1024 MB
   • RHEL 7.9: 1024 MB
   • RHEL 8.3: 1024 MB
   • Ubuntu 20.04.6: 2048 MB
6. Open the Specify virtual hard disk section.

   

7. Select Create a Virtual Hard Disk.
8. Specify the hard disk settings.
   • Specify the location of the virtual hard disk on the host machine.
   • Specify the size of the virtual hard disk according to your chosen operating system:
     • For CentOS 7.8, RHEL 7.9, and RHEL 8.3, specify at least 15 GB.
     • For Ubuntu 20.04.6, specify at least 25 GB.
   • For the Hard Disk File Type and Format, select VDI (VirtualBox Disk Image) or VMDK (Virtual Machine Disk)

   Note Specify additional virtual hard drive space if you plan to install additional software. For best results, Trend Micro recommends selecting VDI (VirtualBox Disk Image).

   Important Do not select "Pre-allocate Full Size" or "Split into 2GB parts." The options may cause the tool to fail.

9. Click Create.
   VirtualBox creates the virtual machine. The new virtual machine appears in the left pane of the VirtualBox Manager screen.

   

   Ensure that the virtual machine is not in any group.
10. Click Settings.
    The Settings window opens.

    

11. Go to System.

    

12. Configure the settings on the Motherboard tab.
    • For Chipset, select PIIX3.
    • For Pointing Device, select USB Tablet
    • Select the following Extended Features:
      • I/O APIC
      • UEFI (Optional)

    Note Select UEFI if you want to create EFI-compatible images. EFI-compatible images are only supported by the following Trend Micro products: Deep Discovery Inspector 5.6 and later Deep Discovery Email Inspector 3.6 and later Deep Discovery Analyzer 6.8 and later Deep Discovery Director 5.1 and later Deep Discovery Web Inspector 2.5 and later

13. On the Processor tab, select PAE/NX.
14. On the Acceleration tab, select Nested Paging.
    If you are using VirtualBox 5.2 and before, also select Enable VT-x/AMD-V.

    Note The Acceleration tab is only available if the processor of the host system supports virtualization technology and the virtualization setting is enabled in the BIOS of the host system. VirtualBox 6.0 and later automatically enables VT-x/AMD-V if the processor of the host system supports virtualization technology and the virtualization setting is enabled in the BIOS of the host system.

15. Go to Storage.

    

16. If Controller: SATA appears under Storage Devices, select the controller and click to remove the SATA controller.
17. Add an IDE controller.
    1. Click and then select PIIX4 (Default IDE).

       

    2. Click the controller and change the Name attribute to IDE.

       

    3. Select Use Host I/O Cache.
    4. Next to Controller: PIIX4, click to create a virtual hard disk.
       The Hard Disk Selector window appears.

       

    5. Select the virtual hard disk file that you previously created and then click Choose.
    6. Click the hard drive you created and verify the Hard Disk attribute is set to IDE Primary Device 0.

       

    7. Click Controller: PIIX4 and then click to create an optical drive.
    8. In the Optical Disk Selector window, click Leave Empty.

       

    9. Click the optical drive you created and verify the Optical Drive attribute is set to IDE Secondary Device 0.

       

    10. Click and select Choose/Create a Virtual Optical Disk…
    11. Select the ISO file containing the operating system installer.
        The ISO file appears as an available device.
    You should only have one Controller: PIIX4 listed under Storage Devices. If there are any other controllers listed, remove the extra controllers.
18. (Optional) Go to Audio and verify that Enable Audio is selected.

    

19. Go to Network and click the Adapter 1 tab.

    

    1. Verify Enable Network Adapter is selected.
    2. For Attached to, select NAT or Bridged Adapter.
20. Go to USB.

    

21. Select Enable USB Controller.
22. Select USB 1.1 (OHCI) Controller.
23. Go to Shared Folders and verify that no folders are shared.

    

24. Click OK.
25. On the VirtualBox Manager screen, click to power on the image.

    

    The installation process starts.
