If in production environment different hypervisor is used, qcow2 image can be converted to various formats using 'qemu-img convert' command. For example, you could make a multiple virtual lab with multiple routers and afterwards deploy the same images in production. These images can be run separately from GNS3 if needed. * Qemu stores images in qcow2 (copy-on-write) format. RouterOS template image file (.img) should also be copied together with the project itself and placed into 'GNS3/images' folder on target machine. * GNS3 stores all project files under one folder which is movable to another computer.

Read more about Wireshark features here. To see traffic on a link in GNS3, right-click on it and chose 'Start capture'. Wireshark is a powerful network packet analyzer which can be used to capture traffic on an interface. * GNS3 installation has Wireshark bundled with it. As GNS3 supports both Qemu and VirtualBox, you can combine instances using both of these hypervisors. One thing to note - Qemu is rather slow in running generic Linux LiveCD's. If full fledged OS is needed, Qemu can run it too. It can be connected to router or switch as necessary. * GNS3 includes VPCS (Virtual PC Simulator) - a simple network testing tool which has some essential commands like traceroute, ping, arp built in. In this guide, we will use separately installed Qemu.Ģ) Install GNS3 (GNS3-1.3.9-all-in-one.exe) and uncheck Qemu During installation, GNS3 will check for existing Qemu installation on your computer and will use that if true. If you want the newest, you can download it from and install separately. Currently, the newest version of Qemu for Windows is v2.4.0, but with GNS3 included is v2.2.0. It is already bundled with GNS3 installation. As a hypervisor GNS3 can use either VirtualBox or Qemu. GNS3 can be run also on Linux and Mac machines.Īs of this writing (August 2015) the newest version of GNS3 is v1.3.9, it can be obtained here - (or just head to ). RouterOS Virtual Labs can be used in various scenarios, for example, to try out configuration before deploying it in production, when preparing for MikroTik Certification test or using CHR as a router for virtual servers, just to name a few.įollowing are basic instructions to get started on creating RouterOS Virtual Labs using GNS3 (Graphical Network Simulator) tool on Windows desktop machine, Windows 8.1 to be specific but it should be similar on other Windows versions as well, just make sure it is 64bit version. Otherwise, it's a fully functional RouterOS. The test version we currently offer has 1mbps limit per interface (in future we will offer unlimited speed with a paid subscription). For more specific studies, we recommend that you use the Cloud structure instead of VPCS.We recently released a test version of our upcoming product Cloud Hosted Router (CHR) - a virtual RouterOS instance for the x86_64 architecture. In this article, we have added VMware virtual computer to the Cloud structure added to the GNS3 workspace.
