cloud images not working with plain qemu/ kvm

[Corin Langosch <corin.langosch@netskin.com>]

Hi guys,

I downloaded the debian cloud images from http://cdimage.debian.org/cdimage/openstack and tried to run them in qemu
using "qemu-system-x86_64 -enable-kvm -smp sockets=1,cores=2 -m 2048 debian-8.2.0-openstack-amd64.qcow2" but the images
don't boot. Here's a screenshot of the boot process: http://i.imgur.com/ZwF3caL.png. There's no more output, it just
hangs there forever.

I tried the qcow and raw images with different versions of qemu (2.4.1, 2.5.0) on different systems (ubuntu 14.04,
15.10). Other cloud images (ubuntu, centos, ..) boot just fine. Of course cloud-init is broken, but that's ok and I
don't have to care about it right now.

I wonder how to get them booting? Do they need any special qemu flags?

Thanks,
Corin
