How To Run Juniper Router JunOS Olive VM image (.OVA) in GNS3

First of all, download, install and run Oracle VM VirtualBox, and GNS3 on your PC.

Secondly, download the JunOS Olive VM image from the link below:

Download JunOS image file for GNS3

(Link searched from internet and pasted here for reference only)

After downloading the JunOS VM image, open the Oracle VM VirtualBox console. Click File and select Import Appliance to import VM (or just double click on the downloaded file and run it with Oracle VM VirtualBox to Import Appliance.)

Now, click the Browse button to locate the downloaded JunOS image file, select it, and then click Next

Accept the default resource values or adjust them as per requirement, and then click Import.(I'm using default values that came with downloaded VM.

Once the VM is imported, select it, and click Start to power on.

Note:
In case, while importing the Virtual Machine in Oracle VM VirtualBox, you get the error "could not start the machine because following physical network interfaces were not found" than click Change Network Settings, select Microsoft KM-TEST Loopback Adapter from the list, and then click OK.
(If Microsoft Lopback Adapter is not already installed, than install it via the "Add Hardware Wizard" on windows and than select it in network settings)

If this error does not occur than, skip this step.

Now, on GNS3, click Edit, and select Preferences. On the Preferences window, select VirtualBox VMs in the left pane, and then select New.Select JunOS Olive VM (Juniper router IOS image)and click Finish.

Now click Edit, change Symbol & Category to Router. Move on to the Network tab, and set the number of adapters as per your requirement (I selected 4 here)

Also, Select the Allow GNS3 to use any configured VirtualBox adapter check box and click OK. Now again press Apply & OK.

Now, in GNS3 console GUI, drag & drop the Junos router and start it.

Switch to the JunOS VirtualBox console or go to console from GNS3. At the login prompt, type root as username and press Enter. The Password is blank
At the next prompt, type cli and press Enter, and "Show Version" to verify the Junos version.

Enjoy.

Now, choose basic disk image for the virtual machine, if you haven’t already chosen/uploaded it to VM than select New Image and give path to Junos.img file and it will start uploading .img file to VM. Give it some time to upload and press Finish. (I had it already uploaded to VM earlier while testing so, chose Existing Image and selected the .img file from drop down menu)
Click Apply and OK
