Actually your intepretation of the callpath is not quite right. The virConnectOpenAuth() method in libvirt.so will end up calling the remoteConnectOpen() method in src/remote/remote_driver.c. This opens an RPC connection to libvirtd, performs authentication, and then calls qemuConnectOpen(). So from that sequence it is the remoteConnectOpen() method that deals with passwords/usernames, not qemuConnectOpen(). If you want to get an idea how to provide username/password via the callback, take a look at the virConnectAuthCallbackDefault() method in src/libvirt.c which is the default impl that just prompts on the terminal console.
