[Qemu-devel] [PATCH v2 1/4] dump: add DumpInfo structure

[Marc-André Lureau]

One way or another, the guest could communicate various dump info (via
guest agent or vmcoreinfo device) and populate that structure. It can
then be used to augment the dump with various details, as done in the
following patch.
