Ok, you can get the CoreFile from that using apport-unpack:
mkdir crashfiles; apport-unpack /var/crash/_usr_bin_qemu-system- x86_64.0.crash crashfiles Then you should be able to use the 'where' command in gdb gdb /usr/bin/qemu-system-x86_64 crashfiles/CoreDump (gdb) where to get more information. Please paste that information here. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to qemu in Ubuntu. https://bugs.launchpad.net/bugs/1464278 Title: Qemu-Libgfapi: periodical shutdown of virtual machines.
