Obviously you compiled QEMU using the experimental TCI (TCG interpreter).
That's not wrong (for debugging some kinds of crashes it is even useful),
but it's slow.

You also called gdb with qemu-system-x86_64, but the core was from qemu-

Which kernel did you use? zImage or kernel-rasptoo? Where did you get it from?
If it is a kernel for an original Raspberry PI, it won't work with QEMU.
QEMU only works with kernels for some other ARM systems.

You received this bug notification because you are a member of qemu-
devel-ml, which is subscribed to QEMU.

  Arm emulation do a crash

Status in QEMU:

Bug description:
  Hello, I have try multiple image for the raspberry pi, with this cli:
  /usr/bin/qemu-system-arm -kernel kernel-rasptoo -M versatilepb -cpu arm1176 
-hda hdd.img -m 256 -append "root=/dev/sda2 loglevel=7 debug" -serial stdio 
  I don't know why, with kvm it say:
  KVM not supported for this target
  No accelerator found!

  I can't debug it with gdb, it crash after the kernel boot (the qemu 
application crash).
  I'm under gentoo:
  [ebuild   R   ~] app-emulation/qemu-kvm-1.0.1-r1  USE="aio alsa curl ncurses
