Anyway I have the bracktrace you requested. I simply started libvirtd, started my vm, killed libvirtd, then started it again with gdb in foreground mode with the breakpoint set. I got a ton of debug info that I posted here: http://www.aptalaska.net/~matt.s/libvirt.txt but the backtrace is simply: Breakpoint 1, 0x00007fffc72a0240 in qemuProcessKill () from /usr/lib64/libvirt/connection-driver/libvirt_driver_qemu.so (gdb) bt #0 0x00007fffc72a0240 in qemuProcessKill () from /usr/lib64/libvirt/connection-driver/libvirt_driver_qemu.so #1 0x00007fffc72a19cd in qemuProcessStop () from /usr/lib64/libvirt/connection-driver/libvirt_driver_qemu.so #2 0x00007fffc72a27d6 in ??
