Description

One way to force a core dump is to kill off ABRT and send core dumps to a known location. I do this with: echo '/tmp/core.%p' > /proc/sys/kernel/core_pattern Then make sure that core dumps are enabled, ie: ulimit -c unlimited Then do whatever it is that causes qemu to core dump, and you should get a core file in /tmp/core.* Are you running qemu directly or via libvirt? If via libvirt you may need to adjust the systemd configuration of the daemon. (See systemd.exec(5)) Can you describe what triggers this? Please provide the qemu command line you are using (/var/log/libvirt/qemu/$vmname.log if using libvirt) Alternatively to Rich's suggestion, you can just 'sudo gdb -p `pidof qemu`' to catch the backtrace No response for a month, closing. Harald, if this is still affecting you, please reopen and provide the info requested in Comment #2 Ah, sorry. Will use the 'sudo gdb -p `pidof qemu`'... stupid me.. didn't think of that. |
