It tends to be not very robust. Especially when the creating/parsing is done ad-hoc and the format changes now and then due to more info needing to be stored later on. The qemu migration format which has almost no structure breaks now and then because of that. Thus I'd prefer to not go down this route when creating something new. cheers, Gerd
