I'm sure there used to be something around to help - but I can't just can't find it at the moment.

Basically you need to: [The following is taken from my book - GNS3 Network Simulation Guide. (Note: When I copy and paste form my copy I loose the diagrams)]

Quote:
Also like Dynamips, you will need more than just Qemu. You will also need a binary copy of the operating system you want Qemu to emulate. And because you want to use GNS3 to configure connections between your Qemu devices and even your Dynamips devices, you will also need a third piece of code called qemuwrapper, which is included with your GNS3 install.
And one more thing. The version of Qemu you run has to be aware of the types of interfaces used in GNS3. GNS3 creates UDP tunnels between devices to allow them to communicate (see Chapter 6, Peeking under the GNS3 hood), so you need a specially patched version of Qemu that knows how to interpret the -net type udp parameter that will be passed to the emulator on startup.

Qemu preferences
Start by navigating to GNS3 Preferences | the Qemu settings | the General Settings tab.
Click on the Test Settings button to ensure that your OS has paths to qemuwrapper, qemu and qemu-img. If not, check your GNS3 install directory and make sure these files are present. If necessary, specify the exact path to each by clicking on the ellipsis (...) next to the field where these paths are defined and find the appropriate directories. Windows users should use the preceding illustration as a guide, Linux users refer to the previous section, and OS X users should use the following:
Path to Qemuwrapper: /Applications/GNS3.app/Contents/Resources/qemuwrapper.py
Path to qemu: /Applications/GNS3.app/Contents/Resources/Qemu-0.11.0/bin/qemu
Path to qemu-img: /Applications/GNS3.app/Contents/Resources/Qemu-0.11.0/bin/qemu-img
If your settings are correct, you are ready to emulate your chosen OS using Qemu. I suggest that you start with a Linux guest, such as Microcore Linux.

@rednectar: you don't need a special patched version of qemu anymore with GNS3; I've successfully tested last stable unpatched qemu release (1.7.1 - compiled from the sources) on Ubuntu 13.10!

Here's my previous post if you need some configuration information regarding its interaction with ASAs: http://forum.gns3.net/topic8866.html

@actionmystique - Have you tested Qemu 1.7.1 with Juniper routers? Does the Juniper "checkpic" script (topic6557.html) still work on all three platforms (Linux, OS X, Windows) with Qemu 1.7.1? I haven't had a chance to test yet.
