[Qemu-devel] [Bug 1331932] [NEW] qemu crash in x86 reload


From: janaki-lappy
Subject: [Qemu-devel] [Bug 1331932] [NEW] qemu crash in x86 reload
Date: Thu, 19 Jun 2014 06:29:10 -0000

Public bug reported:

Hi all,


I am running qemu on an x86 host and when the host reloaded we do see a
core on Qemu and the gdb dump shows as follows.

Can any one please let me know if any one has come across such failures.

rning: Can't read pathname for load map: Input/output error.

Core was generated by `/usr/bin/qemu-system-x86_64 -name default-sdr--2
-S -M pc_q35 -enable-kvm -m 61'.

Program terminated with signal 11, Segmentation fault.
