Step 5: Go back to the GNS3 software to add the IOS file. Step 4: Once the GNS3 VM boots successfully, the IP address of the GNS3 VM will be displayed.
Tip: If the name of the GNS3 VM is “GNS3 VM”, it will be chosen automatically. Click the Import button and wait until the import process completes.On the Import Virtual Machine window, name the new VM as your will, and change its location to a folder on the partition you created just now.Click File > Open, find the GNS3 VM file you downloaded before (the file should be GNS3 VM.ova), and click the Open button.
In this part, I will show you how to set up a GNS3 VM. On this page, you can get the GNS3 IOS images for router 7200 download (c7200 and c7200p) and other popular IOS images (c1700, c2600, c3745, etc.). If you want to download GNS3 IOS images for free, you can try downloading from this page. The images for all of the other platforms that Dynamips supported hit End of Support status, and their images were removed. Note: The only IOS images currently available from Cisco, that will work with the Dynamips emulator are the c7200 images (not the c7200p images!).
The GNS3 VM download should be a zip file, you should extract it. Then, according to the VM software you install, choose a version of GNS3 VM to download. Please go to the GNS3 official website, click the Software link at the top bar, and then click the Download VM for GNS3 link under the Free Download button. GNS3 will not only offer the GNS3 download but also offer a GNS3 VM download corresponding to the version of the GNS3 software you install.

Step 5: Click the Apply button to execute pending operations.ĭual Boot vs Virtual Machine: Which One Should You Choose? Install GNS3 and a VM Program You can keep all of them to the default value if you don’t have specific demands. Step 4: Set parameters for the new partition. Step 3: Right-click the unallocated space and choose the Create button. In the same way, you can take unallocated space from multiple partitions and then put the unallocated space together by moving the location of partitions. Click the partition block and drag it to decide the location of the unallocated space. Step 2: Drag the arrow icon to decide how much space you want to shrink. Right-click a partition and choose Move/Resize. Step 1: Launch MiniTool Partition Wizard and go to its main interface. This software allows you to move the location of partitions to put the unallocated space together. If you need to take enough unallocated space from multiple partitions, I recommend you use MiniTool Partition Wizard. If you can take enough unallocated space from one partition, you can shrink that partition in the Windows Disk Management tool. To manage your GNS3 VM better, I recommend you create a separate partition. To run a GNS3 VM, you should install a VM program first, import the GNS3 VM into the VM software, and then set up and configure the GNS3 VM. To run a GNS3 VM, you should do some preparations.
In addition, because GNS3 does not support full switch functionality or switch IOS images, you will have to configure your router with NM-16ESW switch modules. For example, it’s hard for beginners and you will have to supply your own IOS (Internetwork Operating System) image to import the correct IOS software for the router you are emulating. Of course, GNS3 also has some disadvantages.
Many small and mid-size businesses use GNS3 because this software allows them to create a virtual network right on a PC and conduct experiments with different configurations there rather than on actual hardware. It combines the best features of the existing emulation software (such as Dynamips and Qemu) into a GUI interface and allows you to create an unlimited number of Cisco routing-and-switching lab scenarios. GNS3, short for Graphical Network Simulator-3, is an open-source network software emulator initially released in 2008.
