From f64622c401d4975a56b8559e16286231a1d2cfb8 Mon Sep 17 00:00:00 2001 From: Gleb Natapov Date: Tue, 15 Mar 2011 13:56:04 +0200 Subject: report that QEMU process was killed by a signal Currently when rogue script kills QEMU process (using TERM/INT/HUP signal) it looks indistinguishable from system shutdown. Lets report that QEMU was killed and leave some clues about the killer identity.
