We will, and the solution will be the same: options to create devices as they were in older versions of QEMU. It only needs to cover device features which matter to guests, not every bug fix. However with a machine configuration which is generated by QEMU, there's less worry about proliferation of obscure options, compared with the command line. You don't necessarily have to document every backward-compatibility option in any detail, you just have to make sure it's written and read properly, which is much the same thing as the snapshot code does. -- Jamie _______________________________________________ Virtualization mailing list [email protected] https://lists.linux-foundation.org/mailman/listinfo/virtualization
