You will most likely have a much better user experience using the appliances.You will also encounter fewer errors if you use an appliance rather than trying to configure settings yourself and using untested images.This is because Qemu is better supported on Linux and faster when run with VMware (you can also use KVM).You will be need to provide your own Cisco images to use Cisco devices with GNS3.
Cisco 2691 Ios Image Gns3 License To AccessYou will need to either have an authorized account with Cisco or purchase a VIRL license to access Cisco images like the Cisco ASAv or IOSv. Cisco 2691 Ios Image Gns3 Mac OS And LinuxThe process is similar however for other operating systems such as Mac OS and Linux. Since we want to import the Cisco IOSvL2 VM, select Cisco IOSvL2 in the Appliances section of the Marketplace,in order to download the cisco-iosvl2.gns3a template file. Confirm details of the appliance and then click Download Template. CSR1000v is a virtual router or in other words it runs the IOS software inside a Virtual Environment (in a Virtual Machine), and thats not all because it can run the latest IOS XE software which is the successor of the classic IOS software. Basically all the IOS XE releases which start from 3.x correspond to the new classic IOS 15.x releases, however we will not talk this time about the mappings of IOS to IOS XE software version, if you are interested you can visit the official link on Cisco. Cisco 2691 Ios Image Gns3 Full Machine AndSee the VM settings below on the picture, I decided to give it 3Gig of RAM to the VM which should be a minimum requirement for running the CSR1000v, having a more powerfull machine and giving it more memory would tackle for better performance of the VM for sure, thats up to you. Make sure the IDE Secondary Master is configured to boot the CSR image from your disk at the beginning until it is fully installed and than you can remove this one. I would suggest at this point to stay on General Settings tab and click on the Test Settings button so that GNS3 detects your current VirtualBox settings, after completing this step click on the VirtualBox Guest tab and configure the settings as per below example on the picture (hint: click the Refresh VM List if the VM List doesnt show the CSR1000v). As you can see on the Picture below I have added one CSR1000V and a Cisco 2691 Router and connected them together for testing purposes. Picture is an example of show version command I ran on the CSR1000v from console on GNS3. And most of the CCIE RS training vendors as I see run the CSR1000v on their training sessions, so I believe having a powerful machine running Virtualization you can create your own lab topologies or run the topologies from the Training vendors without any problem using the CSR1000v. In order to have a fully operational CSR1000v use one of the official supported Hypervisors by Cisco like VMware ESXi, Citrix XenServer, Microsoft Hyper-V or KVM.

My only challenge at this point is the ability to console to the device as the others with iTerm on iMAC. I actually got it to work, except feels like something small is still missing Once logged into the router, every time I hit the enter on my keyboard, an sign keeps coming up.
