Hi,
I have a minimal qemu setup that I used for testing development kernels.
I have noticed that somewhere between next-20141013 and next-20141017,
qemu started to hang at boot time, with no messages displayed on the console
(previously, it would boot to a full userspace). I attempted to bisect
it, but the next tree has so many merges that git bisect takes a very
long time. I have attached the config I'm using and have pasted the qemu
command below. The image I'm using is a minimal Wheezy image created
with debootstrap.
qemu command-line:
qemu-system-x86_64 -kernel arch/x86_64/boot/bzImage \
-smp 1 \
-drive file=wheezy.img,if=virtio \
-append 'root=/dev/vda console=hvc0' \
-chardev stdio,id=stdio,mux=on,signal=off \
-device virtio-serial-pci \
-device virtconsole,chardev=stdio \
-mon chardev=stdio \
-display none
Any idea what may have caused this or suggestions for debugging it?
Thanks,
Martin
