The problem is that the image is in a format not compatible with qemu < 1.1. We forgot to convert it to a compatible version before uploading it. You can do two things.
- Convert the image in a machine with qemu >= 1.1 with this command:
$ qemu-img convert -O qcow2 -o compat=0.10 origin.qcow2 destination.qcow2
- Download an older version of the image:
http://appliances.opennebula.systems/rel-4.8/Ubuntu-14.04.qcow2.gz.old
The old version has a problem with loopback device and it does not get IP. Making some services fail.
You can find the fix for the loopback problem in this post:
