    Thank you for your hard work. You helped me a lot to pass the CCNA exam, especially your free course (Udemy – packet tracer Labs).

    How can I use IOU VM on Ubuntu 18.04?

  • Reply Jim October 11, 2019 at 10:52 pm

    Hi, Master! I installed the new GNS3 GUI and GNS3 VM 2.2 from scratch but I had a problem opening the “GNS3 VM.ova” which I fortunately managed to solve. That's why I wanted to share with you, my issue and also the solution, which could be useful to someone else.

    The issue
    ========

    After upgrading the VMware Workstation Pro 12 version to Pro 15.5 and unzipping the “GNS3 VM.zip”, opening the file "GNS3 VM.ova" showed me the following error message:
    "Failed to read from file: GNS3 VM.ova"

    I downloaded the GNS3 VM again 5 times, both from gns3.com and from github. I also unzipped the "GNS3 VM.zip" with several different softwares (7zip, winRAR and the native Windows) but i still had the same problem:
    -> "Failed to read from file: GNS3 VM.ova"

    The workaround
    =============
    1) Rename "GNS3 VM.ova" to "GNS3VM.ova"
    2) Extract the OVA on a linux system by running the command:

    # tar -xvf GNS3VM.ova

    -> you will get the OVF and VMDKs as separate files:
    GNS3 VM.mf
    GNS3 VM.ovf
    GNS3_VM-disk1.vmdk
    GNS3_VM-disk2.vmdk

    (If you want to run a Linux shell system without VMs or emulations, integrated directly with Win 10 and consuming few resources, you could use the magical Microsoft WSL (Windows Subsystem for Linux), version 1. It's free and downloadable directly from Microsoft https://docs.microsoft.com/en-us/windows/wsl/install-win10
    I have installed many real Linux shell distros like Debian, Ubuntu, Fedora, Kali, Alpine and OpenSuse, even with Python 3 virtual environments running like a charm!)

    3) Move the files to your Win 10 system.
    (No needed if you used WSL.)

    4) With VMware Pro 15.5 just open the OVF file

    GNS3 VM.ovf

    -> and that's it!!! The GNS3 VM was sucessfuly imported and now is working.

    My implementation of your GNS3 2.2 Install lab
    =======================================

    After my issue, I Installed and configured IOSv, IOSvL2, IOS-XE (CSR1000v), IOS-XRv, NX-OS and some Linux docker containers
    -> All of them are working together really really well. (I set the GNS3 VM to 12GB RAM, 2 vcpu)

    It was worth the wait for this new version of GNS3!!!!!
    Thanks again David!!!!!

    Slowly transitioning to GNS3 vs Packet Tracer. Thank you for the intuitive tutorial 👍

    David I want to say a big thanks to you for these wonderful videos. Are there videos on how to add sdwan viptela images into GNS3?

  • Reply Thilak S October 12, 2019 at 2:27 am

    There was wide outage for Cisco downloads, randomly threw error while downloading.😊

    Thanks for the tutorial, I had some difficulties and this video helped me out a lot. Question. Why are you running a Mac with Windows 10 in a virtual machine, and GNS3 in the Windows environment. Why not run GNS3 on your Mac?

  • Reply Mike Brooks October 12, 2019 at 3:25 am

    Funny i had to pay $200 for virl images, now it is basically for free.

    Hi David,
    What's the problem of using HAXM and vios images inside Windows? Wasn't HAXM accelerate anything?
