Description Marc-Andre Lureau 2017-09-19 12:23:33 UTC

+++ This bug was initially created as a clone of Bug #1398633 +++

kernel clone for the implementation of this feature.

The qemu consensus is to use a etc/vmcoreinfo fw_cfg entry to store vmcoreinfo details.

The current patch series for upstream:
