      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.

    - 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.

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).

You should be familiar with managing virtual disks in your hypervisor environment. If you are not, refer to your hypervisor manual or contact your hypervisor's support service.

Note: When you add a disk, use a disk type of SCSI or SATA that uses a storage type of:

LSI Logic SAS
LSI Logic, or
SATA

IDE disks are not recommended.

Add a disk to the virtual machine (VM).
Restart the VM.
In the VM console, to obtain the name of the disk devices, enter this command:
```
sysctl kern.disks
```
Assuming ada1 is the device disk added as a secondary disk (note that ada0 is the OS device), execute this command to move the data partition to it:
```
data_move ada1
```
