Is that not correct? No where in your code do you ever invoke eventRemoveCallback. When the stream is "aborted" this just means that libvirtd has released server side resource & reported the error back to the client. You still have to remove your event callbacks otherwise you'll just be invoked forever. See tools/console.c for example code doing what you're attempting, but in C. In particular the places which call virConsoleShutdown. Your code in Python should basically be a straight conversion of tools/console.c from C into Python.
