Alexander Graf 8118f0950f migration: Append JSON description of migration stream ... One of the annoyances of the current migration format is the fact that it's not self-describing. In fact, it's not properly describing at all. Some code randomly scattered throughout QEMU elaborates roughly how to read and write a stream of bytes. We discussed an idea during KVM Forum 2013 to add a JSON description of the migration protocol itself to the migration stream. This patch adds a section after the VM_END migration end marker that contains description data on what the device sections of the stream are composed of. This approach is backwards compatible with any QEMU version reading the stream, because QEMU just stops reading after the VM_END marker and ignores any data following it. With an additional external program this allows us to decipher the contents of any migration stream and hopefully make migration bugs easier to track down.
