In this article, we will deploy the Palo Alto Next-Generation Virtual Firewall directly in GNS3. In the previous article, we deploy the Palo Alto Firewall in VMWare Workstation. As you already know that the GNS3 Network Simulator allows you to directly run KVM machines. So, we will download the Palo Alto KVM Image from the support portal and deploy it in GNS3. So, let’s get started.


How to deploy the Palo Alto Firewall in GNS3

As we already discussed, we need to download the Palo Alto KVM Firewall from the support portal. KVM stands for (Kernel-Based Virtualization Machine). KVM allows you to run .qcow file format directly on it. You need to follow the following steps to deploy the Palo Alto KVM on GNS3:

Step 1: Download the Palo Alto KVM Virtual Firewall from the Support Portal

First of all, you need to download the Palo Alto KVM Firewall from the Palo Alto support portal. Visit the support portal by clicking here. Now, navigate to Update > Software Update. Now select PAN-OS for VM-Series KVM Base Images. In this example, I am downloading the PANOS version 8.1.3. Now, just click on PA-VM-KVM-8.1.3.qcow2  to download the Firewall. You can refer to the below image for downloading the Palo Alto KVM.

After downloading the .qcow file of Palo Alto KVM Firewall, you need to follow the below steps to successfully deploy the Palo Alto in GNS3.

Step 2: Download & Install the GNS3 on your machine

I hope you already aware or you already install the GNS3 in your machine. If not, you can refer the following links to understand & download the GNS3 Network Simulator for Windows or Linux machine. Basically, GNS3 is a Great Network Simulator tool on which you can run many Network & Network Security appliances.

Step 3: Deploying the Palo Alto VM Image in GNS3

Now, we are ready to deploy the Palo Alto KVM Image in the GNS3 simulator. Currently, I’m using GNS3 2.1.21, although, the KVM deployment is the same on other GNS3 versions too. Open the GNS3 and, Navigate to Edit >> Preferences >> QEMU >> Qemu VMs and click on New. Now, give the friendly name to this VM, i.e. PaloAlto_VM and click on Next.


Now, give the RAM to the Palo Alto VM Firewall. In this example, I am giving 4 GB RAM to the VM Image and Click on Next.

Note: Minimum requirement for Palo Alto VM Firewall is 4 GB Ram & 2 CPU Core!


Now, you need to select the Console Type. In KVM we can get the Firewall CLI just by double-clicking. So, here, I’m selecting telnet. However, if you have a vnc application installed on your machine, you can select the vnc and click on Next.


Now, In the last step, you need to select the image file you downloaded in Step 1. It will prompt to copy that file in the GNS3 default directory, so you can copy it on the gns3 default directory, it’s recommended. Now, click on Finish.


Now, before applying your changes, you need to change the Interfaces of the VM Firewall. In this example, I am using 8 different Interfaces on the VM Firewall. However, you can change it according to your requirements. To change it, navigate to Edit >> Network (you can refer to the given image). Optionally, you can select a Palo Alto icon, for this VM Image. I’ve one .svg file fo the Palo Alto, so I am choosing the same here.

By default, only 1 CPU  Core is configured for PA VM. So, access the General Setting Tab on the same opened window, and configure 2 CPU Core for the Palo Alto Firewall. You can refer to the below image for this configuration.



Once, you applied you the changes, you will find that a new Palo Alto Firewall is ready along with your already installed appliances. Just drag down the firewall in the Project area. Right-click on this and choose the start option. Once, you start the VM, you will get the console of the Firewall, which is in the booting process.


Step 4: Configuring the Management Interface of Palo Alto KVM (Virtual Firewall)

In the previous step, we successfully step the Palo Alto VM in the GNS3. Now, we need to double click the VM appliance we just deployed. You will find that the Virtual Palo Alto Firewall booting process is going on. Once the Palo Alto VM Firewall finished the booting, you need to give the default credentials to the VM.

Note: The default username is admin and password is admin. Palo Alto Firewalls takes time to complete the boot process!

Now, we need to configure the management interface so that we can access the GUI of the Palo Alto VM. You need to follow the following commands to configure the IP address on the management interface.

To assign the IP address & services, you have to follow given commands:

set deviceconfig system type static
set deviceconfig system ip-address netmask

The snapshot of the whole configuration is given below:


Now, you are ready to get the GUI of the Firewall. So, just follow the next step to get the GUI of Palo Alto.

Step 5: Accessing the Palo Alto KVM Firewall from the End Machine

In the previous step, we have done all configuration which is used to get access to the Palo Alto VM. Here, I’ve windows 7, connected like below image:

I need to provide the statically IP address in the same network on Windows 7. In our Palo Alto KVM Firewall, ethernet1 is configured with, so I’ll configure the IP address on the Windows7. So, my windows 7 IP configuration looks like this:


Now, test the connectivity with the Palo Alto KVM. Let’s initiate the ping to the Palo Alto VM IP address, i.e.


Now, Let’s open your favorite web browser and access the Palo Alto KVM using A certificate warning page will appear, you need to Proceed with it. If everything is perfect, you will get the GUI of the Firewall. The Fresh KVM Deskboard is looking like below image:




That’s it! We have successfully deployed the Palo Alto KVM in the GNS3 Network Simulator.

In this article, we configured the Palo Alto Virtual Firewall directly on GNS3 Network Simulator. First, we download the Palo Alto KVM Virtual Firewall from the Palo Alto support portal. Then, we successfully imported the Palo Alto Firewall on GNS3 Simulator. We configured 8 different Interfaces for different purposes on Palo Alto KVM. However, you can install many more Network Interfaces. We configured the management interface of the Palo Alto Firewall to gain access from the PC. Finally, we get the Palo Alto VM Firewall GUI on our end machine.

    Great guide, I’m just missing the steps you took to install the windows 7 machine.



    1. Hi Kim!
      Glad to know this helps you. Windows 7 is installed in VMWare Workstation. So, I connected the Palo Alto Firewall and Windows 7 using U-bridge. However, you can also download .hda the file of Windows 7 to deploy it directly in GNS3.
