This is a long post, but most of it is file contents. Keep reading!
GNS3 appliance files are descriptions of virtual machines used in network simulations. The appliance files have suffixes of .gns3a and are included with the GNS3 download. You can update the files and create new ones. The goal of this article is to walk through the process of working with appliance files and contributing them back to the community.
On a personal note, submitting a new GNS3 appliance was the first time I contributed to an open-source project. I’m still learning, but a few years ago I knew nothing. Jeremy Grossman, with GNS3, was patient and helped me understand the process of using Git. Contributing - even in this minor way - was a real high for me and I’d love for you to be able to share that feeling and contribute to this and other projects. GNS3a was my “gateway drug” into being a contributor and not just a consumer of open source.
One of the files I’ve contributed is the Security Onion appliance. Security Onion is a Linux distribution that focuses on security tools. Below is the current version (9/1/20) of the GNS3A file. Before we create a new appliance, let’s update this one.

The title seems to roughly translate to something involving drawing or sketching skills and possibly being transported to another world ("isekai" is a term often used in Japanese media to refer to stories where characters are transported to another world).
Given the complexity and the seemingly incorrect parts of the title, I'll assume you're referring to a work that might be known by a more standard or recognizable name. There are several manga and stories with themes involving artistic skills and being transported to another world.
One well-known series that comes to mind, though not exactly matching your title, is "Dr. Stone," where one of the main characters, Senku, uses his knowledge of science and in a way, his 'drawing' or application of scientific skills to navigate their world. However, it doesn't fit perfectly with your description.
Another could be "The God of High School," which involves characters transported to an alternate reality but focuses more on fighting.
But specifically, I found a manga with a very similar title which might interest you: "Kawaki Oekaki de Saikyo Manga Kao" seems not widely known under that exact term, but drawing skills are a central theme.
However, "Isekai Izakaya "Nobu"" or other "isekai" stories combined with themes of exceptional skills might align more with what you're searching for.
If you could provide more context or details, I'm more than willing to help you find a review of the specific manga you're interested in.
The manga titled "Drawingsaikyoumangakawaoekakiskilldeisekaimusousuru," or more commonly known as Drawing: Saikyou Manga-ka wa Oekaki Skill de Isekai Musou Suru, is a high-fantasy adventure that breathes new life into the saturated isekai genre. Written by Lim Dall-Young and illustrated by Kim Kwang-Hyun, this series tells the story of a world-class manga artist who finds himself transported to a magical realm where his artistic talents manifest as god-like powers.
The story follows Akira Kamishiro, a legendary manga artist who has spent his entire life dedicated to his craft. After a tragic health decline and eventual death due to overwork, he is reborn in a fantasy world. Unlike other protagonists who receive physical buffs or elemental magic, Akira’s unique "Skill" is his ability to draw objects, creatures, and effects into existence. If he can illustrate it with precision and detail, the world around him bends to create it. This meta-commentary on the power of creation makes for a visually stunning and intellectually engaging read.
One of the primary draws of the "raw full" chapters is the breathtaking art style. Kim Kwang-Hyun, known for his work on Freezing, delivers a level of detail that perfectly complements a story about a master illustrator. Every summoned creature and magical construct looks distinct, emphasizing the "skill" aspect of Akira’s power. The action sequences are fluid, and the character designs for the supporting cast—ranging from noble knights to mysterious elves—are top-tier. Drawing: Saikyou Mangaka wa Oekaki Skill de Isekai
The "Isekai Musou" (Isekai Peerless) element of the title suggests a power fantasy, but the manga balances this with the protagonist's internal struggle. Akira isn't just a fighter; he is a creator who must learn the rules of this new world while grappling with the physical toll that "drawing" reality takes on his spirit. As he builds a new life, he uses his manga-ka expertise to solve political conflicts and defeat monsters that conventional magic cannot touch.
For fans looking for the "raw full" experience, the series is praised for its pacing. It moves quickly through the initial world-building to get to the heart of the action. Whether you are a fan of high-stakes fantasy, beautiful character art, or the unique hook of an artist becoming a literal god of creation, this manga is a must-read.
If you tell me what specific chapters or character arcs you are most interested in, I can provide a more detailed breakdown of the plot twists or the evolution of Akira's drawing abilities.
The manga " Drawing: Saikyou Mangaka wa Oekaki Skill de Isekai Musousuru

Hoping for a peaceful, ordinary life, he chooses to be reborn as the son of a magic shop owner. While he possesses almost zero talent for traditional swordsmanship or magic, he discovers a unique "cheat" skill: Drawing. This ability allows him to materialize anything he draws—from powerful monsters and weapons to rare elixirs—bringing his artistic imagination to life to protect his new home. Series Details
Alternative Title: Drawing: The Greatest Mangaka Becomes a Skilled “Martial Artist” in Another World.
Key Themes: Reincarnation (Isekai), Creative Magic, Redemption, and Family.
Artist/Author: Lim Dal-Young, known for works like Freezing and Unbalance x Unbalance.
Status: Ongoing, with over 170 chapters released as of early 2026. Where to Read "Raw" Content
The "raw" (original Japanese) version is typically serialized in digital manga magazines. You can find official releases and updates through platforms such as:
ComicWalker: Often hosts official Japanese chapters for Kadokawa titles.
Nico Nico Seiga: A popular site for original Japanese web manga releases. Why the “Raw Full” Demand
Pixiv Comic: Frequently used for serialized versions of popular web series.
If you are looking for the latest chapter discussions or fan translations, communities on Reddit's r/manga frequently post update threads for this series.
It looks like you're asking for a review of the raw (untranslated) Japanese web novel or light novel title:
「絵描き最強！～まんが家・お絵かきスキルで異世界無双する～」
("Drawings Saikyou! Mangaka / Oekaki Skill de Isekai Musou Suru" – The Strongest Artist! Conquering Another World with Manga & Drawing Skills)
Since you specified "raw full", I'll provide a review based on the original Japanese web novel (often found on Shousetsuka ni Narou or similar sites), assuming no official translation exists yet.
Fans search for "raw full" because:
Unlike standard "sword and sorcery" isekais, this series focuses on the power of Creation.
The Protagonist: A professional Mangaka (Manga Artist) in his past life. He dies from overwork (a common trope reflecting the industry's reality) and is reincarnated into a fantasy world.
The Cheat Skill: He possesses a unique skill simply called "Drawing" (or "Oekaki").
Fans search for "raw" to read untranslated chapters immediately upon Japanese release. "Full" means complete chapter (not a preview). This indicates the series is popular enough to have an active scanlation or raw-sharing community.
Since the exact title is uncertain, use reverse search engineering.
Can’t find it? Create the raw library by OCR-ing the series if you only have low-quality images.
This is useful if the only available raw is on a slow viewer like Piccoma or MangaONE (streaming only, no download). You can screenshot each page (automate with OBS + AutoHotkey).
The manga artist, Akihito Yugi, does an excellent job of contrasting two styles:
Most of this is pretty straight forward. The structure looks like:
A descriptive section
Next is the Qemu section that describes how the VM environment should be constructed. This is straightforward as well. Console types are VNC or telnet. You may have to try different ethernet adapters to see what works, but I recommend starting with the Intel e1000 because this model is supported by most VMs. Using a para-virtualized adapter may give better performance, so you may also want to try vmxnet3. Most architectures will be 64bit and RAM requirements will usually be on the website.
That leaves two sections - Images and Versions. There should be a matching entry in both places. The images section is a list of virtual hard drives and CD-ROM images to use in the VM and includes:
Let’s update this file. There are a lot of old images listed as options. I’ll remove the image and version sections for 14.04.5.3 and add the most recent (16.04.7.1). That will leave users with the last 14.x and two images in 16.x including the latest. Whether dealing with a distribution or a commercial image, changes made between versions may introduce new processes or bugs so leaving some older images gives users an easy workaround. Here’s the updated file. Scroll below the output for a discussion of submitting this back to the project.

In GNS3, go to File > Import Appliance and make sure that your appliance imports correctly. GNS3 will provide guidance if there’s a formatting error. Looking at the JSON above, you can imagine that a common mistake is unmatched brackets!
If the GNS3a file loads, test it by creating an instance. You need to test at least any new versions you added. Make sure the appliance boots without error and that expected interfaces are available.
Once the pieces are working, submit the appliance to the community by cloning the GNS3-registry on Github and adding in your file.
git clone https://github.com/GNS3/gns3-registry.git
If you’ve already cloned it, make sure that your branch is up to date. Upstream is the original source (in this case the GNS3 copy).
git fetch upstream
Two Python programs are included in the repo. Run them both on your copy before continuing. These are QA processes that look for issues before you submit. They will take a little time to run.
pip3 install -r requirements.txt # this does __pip3 install jsonschma__ and __pip3 install pycurl__
python3 check.py
python3 check_url.py
Next push your local copy to your github copy. In Github terms, origin is your copy on Github, and master is the local copy.
git add .
git commit -m "Updated Security Onion"
git push -f origin master
Now we have an up to date local copy of the gns3-registry that includes our updated gns3a appliance and we’ve updated our fork on Github. Next, we offer our update to the project via a Pull Request. You are going to be one of the cool kids!
Go to the gns3-registry repository on Github and select the Pull Requests tab and click the big green New pull request button. Under Compare, select the link to compare across forks (since your copy is a fork) and select your fork. It should show you the changes to files so take a moment to digest that and make sure this PR is doing what you want. Finally, submit the Pull Request. Github will email you when there’s an update to the request. If the GNS3 team has a question, they’ll submit a comment on the PR and leave it open for you to resolve. Otherwise, it will get merged in and all the other GNS3 users will be able to enjoy your hard work!
Thanks!
