Once I got my idlepc set up correctly, the CPU never EVER goes above 40% - I could probably get away with even less RAM as well, 4GB was overkill. I usually put exec-timeout 0 0 under all the console lines to keep this from happening. For some reason this seems to trigger Dynamips to go to 100% CPU. http://etherealmind.com/control-cpu-usage-in-gns3-dynamips-with-process-lasso/ Packet Pushers Weekly A podcast on Data Networking where we talk nerdy about technology, recent events, conduct interviews and more.

I'm not sure about the magic behind this, maybe someone with more expertise in Dynamips can explain this but lowering this value dramatically decreases the CPU usage. I could probably get rid of this if I allocated more memory but I only have 4 GB on my laptop.

I tried doing idel pc value, but hasn't been much of help. How many hypervisors are you running? There is a value called idlemax which is related to the famous idle-PC value.

that works great for me.

I don't know if putting this in your .net files will work but I'm thinking if idle_max somehow gets set this should too.

I just pick up asus m5a97 motherboard with amd fx 8120 8 core and 8GB ram hope it will do the job. Very nice find! I have to shut/unshut interfaces to make this working or even sometimes to restart the whole lab. Otherwise I would recommend getting some more memory or try runnig Linux instead, it is more stable.
