Hi,
Same problem here
qemu-kvm-0.12.x hangs if I have at the same time "-no-kvm" and
"file=essai-slitaz.raw,if=ide,index=0,boot=on" sometime with the message
below
but
qemu-kvm with "-no-kvm" and without "boot=on" option for the file
parameter, works
qemu-kvm with "boot=on" option and kvm enable works. (kvm-kmod is 2.6.32.7)
Unfortunatly, I am using libvirt which always set "boot=on" on the file
parameter, so I have to downgrade qemu-kvm to 0.11 version

I have to confirm this issue: Something badly crashes here as well,
either grub or the extboot ROM or Seabios.
Does anyone has a good idea what makes the difference here, ie. where to
start debugging?

May be TCG interprets something incorrectly in extboot.bin. Sounds
unlikely, but symptoms look like this is the case.

Yes, maybe. I'm currently building a debug version that has support for
TCG block tracing enabled. Should get us closer to the crash.

Looks like the old story again: extboot tries to write to ROM (old_int13
and old_int19 variables). That happens to work due to KVM limitations,
but breaks once true protection is established. Don't we have some heap
managed by Seabios that extension ROMs can use?

Hi,
With this small disk image:
http://psy.jim.sh/~jim/tmp/diskimage.gz
and the new qemu-kvm-0.12.2:
$ kvm --version
QEMU PC emulator version 0.12.2 (qemu-kvm-0.12.2), Copyright (c) 2003-2008 Fabrice Bellard
I can successfully boot to a "grub> " prompt with:
$ kvm -drive file=diskimage,boot=on
However, if kvm gets disabled:
$ kvm -no-kvm -drive file=diskimage,boot=on
then the boot hangs at "GRUB Loading, please wait..." and consumes 100% CPU.
