Then you need to run 'virsh destroy 4' in a different console so you reproduce the crash. After this, when you return do gdb you should see a stack trace. It will point to line which caused the trouble. If not, you may need to install libvirt debug infos (actual command to do this is distro specific). Btw: you can join steps 3 and 4 into one: gdb -p $(pgrep libvirtd) Once you have the stack trace and the logs, please do open a new bug against libvirt: https://bugzilla.redhat.com/enter_bug.cgi?product=Virtualization%20Tools and attach the stack trace and the debug logs.
