From 2da91b54fe98faa8676264ac6e5a3aac5b69bec2 Mon Sep 17 00:00:00 2001 From: Viktor Prutyanov Date: Thu, 17 May 2018 19:23:39 +0300 Subject: dump: add Windows dump format to dump-guest-memory This patch adds Windows crashdumping feature. Now QEMU can produce ELF-dump containing Windows crashdump header, which can help to convert to a valid WinDbg-understandable crashdump file, or immediately create such file. The crashdump will be obtained by joining physical memory dump and 8K header exposed through vmcoreinfo/fw_cfg device by guest driver at BSOD time. Option '-w' was added to dump-guest-memory command. At the moment, only x64 configuration is supported.
