In the Virtual Voice lab series, I am using an Ubuntu Linux environment.  To eliminate permissions issues, it is best that you run GNS3 as root.

Here are a couple issues I have experienced when running GNS3 as a normal user.

Not able to start dynamips.
Error msg: Can’t Connect to the hypervisor on port 7200

Not able to connect to a cloud object.
Error Msg: 206-unable to create Linux raw ethernet NIO
Error Msg: 206-unable to create Linux generic ethernet NIO
Error Msg: 206-unable to create UDP NIO
