Popular Post w1z4rd Posted March 28 Popular Post Share Posted March 28 Downloaded the two images. Installed the L2 image in GNS3 on my Ubuntu laptop. I gave it 640MB or RAM and it worked just fine. My only issue is that GNS3 cannot push a template startup-config. So you have to create the IOL device and do not define a Startup-config. To get the file to work with GNS3 on Ubuntu, I also renamed the file to give it a .bin extension. Also, you need to give the file executable permissions: This is the hidden content, please Sign In or Sign Up At the end, I got the following: This is the hidden content, please Sign In or Sign Up Thanks a bunch @netkillui! 120 23 3 2 Link to comment Share on other sites More sharing options...

I did manage to get the IOL L2 image to run on GNS3. I run my GNS3 images directly on my Ubuntu host. I guess the way I do it must be very similar to how you would do it when using the GNS3 VM. When I first tried running the IOL L2 image, it would not run because the image was not an executable. I thus had to `chmod +x` the file. After that, I managed to add it into GNS3 as an IOL device, with no issues. But when I tried running it, GNS3 threw an error. I think the problem that GNS3 had in the beginning was actually writing the startup-config into the switch's NVRAM (or flash, whatever). GNS3 just couldn't do it and it threw an error. (I am not exactly sure but, if I remember correctly, the error was something like "GNS3 could not find nvram in the expected location"). Well, I thought, the only reason that GNS3 is looking for the nvram during bootup, to begin with, would be to put the startup-config in there. I knew it wasn't the IOL image that couldn't find its NVRAM, because it was GNS3 that was complaining, not the IOL itself. So I went to the device's settings in GNS3, and told GNS3 to not use a startup-config. To be sure that the issue had nothing to do with the VM's RAM, I also bumped RAM to 614 MB. I started the switch, and it worked. It actually boots up pretty fast too. I later tried 512 MB RAM, and that worked as well. I tried the L2 IOL because my experience that those ones are a little harder to get to run, and have not yet tested the IOL L3 image. Are you getting an error message when trying to run the L2 image in GNS3? Can you post the error here? And how much RAM did you give it? 1 Link to comment Share on other sites More sharing options...

But for completeness' sake, try the following: `sudo` is a fairly common tool in Linux. As far as I can tell, Ubuntu has always included `sudo`, and since the GNS3 VM is based on Ubuntu, I would be very surprised if `sudo` didn't work in the GNS3 VM shell. To see how `sudo` works, try the following within the GNS3 VM: This is the hidden content, please Sign In or Sign Up `sudo` will ask for your password, and if you provide the `gns3` user's password, you should get the directory contents. Then try the 3 following, separate commands: This is the hidden content, please Sign In or Sign Up Another thing you can try is to copy the .yaml file that you can find with the image into the same directory as the image (/opt/unetlab/addons/iol/bin/ in your case). 58 6 2 2 Link to comment Share on other sites More sharing options...
