    - 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.

      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.

Install a virtual machine

Do this procedure to install a virtual machine (VM).

Make sure that:

The virtual machine (VM) operating system (OS) is set to FreeBSD 12 or later versions (64-bit)
The VM compatibility version is set to 15+, such as ESXi 7.0 or later (i.e., VM version 17), if possible; however, this depends on the VSphere version level

To install the VM in the hypervisor, you need to configure the VM to enable external access. If you are not familiar with how to import the open virtual appliance (OVA) VM in your hypervisor environment, refer to your hypervisor's manual or contact your hypervisor's support service.

These disk storage types are recommended and supported:

LSI Logic
LSI Logic SAS
SATA

Important: Nozomi Networks Operating System (N2OS) does not support VMware Paravirtual SCSI (PVSCSI) storage type.

Important: N2OS does not support the IDE storage type.

Make sure that you are familiar with the minimum resource requirements.
Import the VM in the hypervisor and configure the resources.
Wait for the VM to finish importing.
In the hypervisor settings for the VM disk, set the desired size.

Note: Some hypervisors, such as VMware ESX >= 6.0, permit you to change the disk size at this stage.
If your hypervisor does not permit you to change the disk size at this stage, do not continue with this procedure until you have completed the procedure: Add a secondary disk to a virtual machine.
Boot the VM.
The VM boots into a valid N2OS environment.
Log in as admin.
You are logged in instantly as no password is set by default.
To go to privileged mode, enter this command:
```
enable-me
```
You can now perform system changes.
