Any specific information on what the guest was doing? Was it doing heavy I/O or was it idle? Are you using IDE emulation or virtio-blk? Please provide a backtrace: 1. Build with ./configure --disable-strip (or use matching -debuginfo packages from your distro) 2. Run with gdb --args path/to/qemu [...args...] When the abort happens please use the "bt" GDB command to display a backtrace. Stefan
