Bug description:
When doing QA for SUSE on bug 1177830
I found that the fix is incomplete,
because it assumed that the cached image would be mostly sparse.
However, I can easily create non-sparse small compressed qcow2 images
with
perl -e 'for(1..11000){print x x 1024000}' img
qemu-img convert -c -O qcow2 img img.qcow2
glance image-create --name=11gb --is-public=True --disk-format=qcow2
--container-format=bare img.qcow2
nova boot --image 11gb --flavor m1.small testvm
which (in Grizzly and Essex) results in one (or two in Essex) 11GB large
files being created in /var/lib/nova/instances/_base/
still allowing attackers to fill up disk space of compute nodes
because the size check is only done after the uncompressing / caching
