I'm playing around with IOU nodes, and I noticed that I had to change my image from a IOU L3 image to an IOU L2 image. So, I stopped the IOU node, reconfigured that IOU node to use a IOU L2 image, and started it again .. however it would show an error after starting that image again on the 'gns3server' output:

[I 140526 21:27:50 iou_device:273] IOU SW1 [id=1]: iouyap path set to /usr/local/bin/iouyap

[I 140526 21:27:51 iou_device:580] stopping iouyap PID=4560 for IOU instance 1

If I revert back from the IOU L2 image to the IOU L3 image, everything goes back to normal and that IOU node boots up normally.

Anyway to change how the IOU image without starting a new topology from scratch?

I don't think you can switch between L2 and L3 IOUs, especially when a nvram file already exists. The error you see most likely results from an IOU crash. To confirm this, please go to
/root/GNS3-Proj/iou/device-1/ copy your iourc file there and start L2IOU:

/var/dynamips/images/iou/i86bi-linux-l2-ipbasek9-15.1g.bin -e 8 -s 0 1

Let me know about the result.
