Processor: 2 or more Logical cores – AMD-V / RVI Series or Intel VT-X / EPT – virtualization extensions present and enabled in the BIOS. More resources allow for larger simulation

Some appliances are designed to only run in VMware. Also, there are times when you may simply prefer using a desktop VM (and the GUI applications it can provide), instead of using the serial console to work with the VMs CLI in a terminal. Desktop VMs are more responsive in VMware than Qemu, purely due to technical reasons that are beyond the scope of this document. What about VMWare Fusion? ​ The link indicators for Suspended devices will turn yellow. Suspended devices still have any non-saved configuration changes stored in your system RAM, and while switch to a powered on state faster than stopped devices will (again, this will also be reflected in the Topology Summary). This guide applies to both the Local Server and GNS3 VM installations. Both installation options use the same user interface for the management of projects. Screen Layout ​ Modern replacement to WinPCAP know to fix issues with Win10 but is less tested than WinPCAP. Install Npcap with the “WinPcap API-compatible Mode” option selected, if using without WinPcap. Npcap can co-exist with WinPcap, if that option is not selected. An Open project window will display. Navigate to the GNS3 projects folder. By default this is C:\Users\\GNS3 in Windows:You may need to create an exemption/exclusion in your anti-virus software to allow this executable to run. This process varies, so consult the documentation of the anti-virus suite you use for instructions.) Something to bear in mind, is that these shapes will initially be placed on a higher layer than devices already in the topology workspace, so they’ll obscure devices already present: If you will install the GNS3 server on the local system without a virtual machine, select the following components and tools. Dynamips is an older technology that emulates Cisco hardware. It uses real Cisco IOS images. It is good for basic CCNA type topologies, but has a number of limitations such as only supporting older Cisco IOS versions (12.X) which are also not supported or actively updated by Cisco. GNS3 will search the GNS3 images directory by default. If the file is not found, you will need to navigate your filesystem to find that file.

We are not discussing the importing of the GNS3 VM in this document; but rather the addition of other virtual machines to GNS3 topologies which may be running in the GNS3 VM or running locally. VMWare Limitations in GNS3 ​Drag and drop the selected node (device) to the GNS3 Workspace. An instance of the node becomes available in the Workspace. In this example, the TinyCore PC is now available: Used to avoid QEMU using 100% of your CPU (when it is running) in some cases like with the old ASA devices
