Re: [libvirt] [PATCH v4 1/5] libvirt: Define domain crash event types



Applied and tested successfully on s390x platform (as expected by me).

Eric mentioned already the few points that should be corrected (indentation of comments).

Indentation looks odd, but that's a trivial fix.

Might be better as merely "crashed"

Overall, looks like a reasonable set of additions in isolation, but I'm
still trying to figure out if support for xen panic detection already
had existing events that we should be reusing, instead of adding new
events just for qemu.
