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. With this VM, you can do experiments with different configurations there rather than on actual hardware. This post from MiniTool shows you how to install and run GNS3 VM. It can allow you to create a virtual network right on a PC.
