On Thu, Jul 14, 2011 at 5:43 PM, Constantine Chernov path/myimage. qcow2.img, boot=on, if=scsi, media=disk, bus=0,unit= 1) unexpectedly crashes without core dump. When the image is connected as an ide disk (-hda ) vm flies normally.

Please post your full QEMU command-line.
Did you enable core dumps before launch QEMU? Do "ulimit -c
unlimited" in the same shell before running the QEMU command-line.
If it is exiting instead of crashing I suggest launching QEMU from gdb
and catching the exit:
1. Install qemu-kvm-dbg to get the debuginfo for useful backtraces
2. Start gdb with QEMU and its usual command-line arguments: gdb
--args qemu-kvm ...
3. Set breakpoints on exit(3) and abort(2):
b exit
b abort
4. Run the VM and reproduce the exit:
r
5. When it exits you will hopefully be at an exit/abort breakpoint and
can print the stack trace:
bt
Please post the backtrace so we have more information on how the exit happens.
Thanks,
Stefan
