Deploy the ExtraHop Command Appliance on a Linux KVM
This document provides information on how to install the ExtraHop Command virtual appliance on a Linux kernel-based virtual machine (KVM). This guide assumes that you are familiar with basic KVM administration.
If you have not already done so, download the ExtraHop Command virtual appliance file for KVM from the ExtraHop Customer Portal.
Important: | If you want to deploy more than one ExtraHop virtual appliance, create the new instance with the original deployment package or clone an existing instance that has never been started. |
Requirements
Before you can install the ExtraHop virtual appliance, make sure that your environment meets the following requirements:
- A KVM hypervisor environment capable of hosting a VM that has:
- 4 GB RAM
- Two vCPUs
- One 4 GB boot disk (virtio-scsi interface recommended)
- One 40 GB datastore disk (virtio-scsi interface recommended)
- An ExtraHop virtual appliance license key
Package contents
The installation package for KVM systems is a tar.gz file that contains the following items:
- ECA_KVM.xml
- The domain XML configuration file
- extrahop-boot.qcow2
- The boot disk
- extrahop-data.qcow2
- The datastore disk
Determine the best bridge configuration
Identify the bridge through which you will access the management interface of your Command appliance.
- Make sure the management bridge is accessible to the ExtraHop virtual appliance and to all users who must access the management interface.
- If you need to access the management interface from an external computer, configure a physical interface on the virtual management bridge.
- (Recommended) Configure separate bridges for the Command appliance management bridge and any bridge you will capture network traffic through on other ExtraHop appliances.
Edit the domain XML configuration file
After you identify the management bridge, edit the configuration file, and create the ExtraHop virtual appliance.
Configure a static IP address
By default, ExtraHop appliances ship with DHCP enabled. If your network does not support DHCP, you must configure a static address manually.
Post-deployment actions
Note: | Log into the Web UI with the setup user account and type default for the password. |
- Review the Discover and Command Post-deployment Checklist and configure additional Command settings.
- Connect the Command appliance to your Discover appliances.
