Thanks everyone for the comments on the subject! I admit I am not actually 'passionate' about file formats, but I do agree with those who said that using *qemu* to save a VM is ugly. I personally think that it would be yet another dangerous precedent for the idea that qemu should be used for stuff which are completely unrelated with hardware virtualization. As for the file formats, I think ELF idea is cute: modular, extendible, versioned, and easily writable by libelf. Let me know if you have further comments, and please note that I am just starting to work on a general overhaul of save/restore code, so it will take a while for me to get some code out of this talk. Thanks, Gianluca -- It was a type of people I did not know, I found them very strange and they did not inspire confidence at all. Later I learned that I had been introduced to electronic engineers.
