I have been using GNS3 since last one year successfully. All of a sudden today when I created a new lab (which have total 14 nodes of having IOS 3700) nodes have stopped saving the config. after shutdown or reboot. Some nodes are even not saving basic config. of passwords & banners and some are saving basic but not interface config. Please suggest a solution or a reason why its happening. Thanks
This is a great error faced me for three days.
The answer is :
I will add that I in general will first issue wr command to save the configuration files in each router first.
