    - Virtual installation
      Before you install a virtual machine (VM), you should make sure that you are familiar with the minimum requirements, and the supported formats and software that you can use with the Nozomi Networks software products.
    - Virtual machine sizing
      A description of the virtual machine (VM) sizing requirements for Nozomi Networks sensors.
    - Guardian sizing recommendations
      The following table gives recommended sizes for instances running the Guardian.
    - Check the RAM of a virtual machine
      The amount of random-access memory (RAM) from the hypervisor might not correspond with the actual amount seen from within the virtual machine (VM). Therefore, it is important to confirm that your VM has sufficient RAM to support your configuration.
    - Install a virtual machine
      Do this procedure to install a virtual machine (VM).
    - Expand a disk on a virtual machine
      The monitoring scope of your sensor will dictate the size requirements of your virtual hard drive. Do this procedure to adjust the size of the virtual hard drive.
    - Add a secondary disk to a virtual machine
      If the main disk is not large enough when it is first imported, you can do this procedure to add a larger virtual data disk to the virtual machine (VM).
    - Add a monitoring interface to the virtual machine
      By default, the virtual machine (VM) has one management network interface and one monitoring interface. Depending on deployment needs, it might be useful to add more monitoring interfaces to the sensor.
