Public bug reported:

Description:
=============
During spawning of cirros kvm instance on kvm compute node, I am getting below exception:
ImageUnacceptable: Image 99aec143-35db-41d1-9c1d-020832cc5dea is unacceptable: 'qemu-img info' parsing failed

Steps to reproduce:
====================
1) Create network
2) Create subnet
3) Fetch cirros image from below link:
   wget http://download.cirros-cloud.net/0.4.0/cirros-0.4.0-x86_64-disk.img
4) Create qcow2 image using below command:
   glance  image-create --name 'cirros-new'     --container-format bare --disk-format qcow2 --property    vmware_disktype=sparse --property vmware_adaptertype=ide   --property hypervisor_type=qemu --visibility public < cirros-0.4.0-x86_64-disk.img 

5) Boot an openstack instance using below command:
   nova boot --flavor 1 --image 99aec143-35db-41d1-9c1d-020832cc5dea --nic net-id=a9f6015e-e736-4f77-b5cb-2c3ee2fe76d2 cirros-vm-1

6) Now vm Goes into ERROR state.

+--------------------------------------+------+--------+------------+-------------+----------+

Expected Result:
================
qemu-img should return output like:
$ qemu-img info /opt/stack/data/nova/instances/_base/59b8ce75fe0be35c095dedfca62a6fee9611bfe5 --force-share
image: /opt/stack/data/nova/instances/_base/59b8ce75fe0be35c095dedfca62a6fee9611bfe5
file format: raw
virtual size: 39M (41126400 bytes)
disk size: 18M

Actual Result:
==============
I am not sure why qemu-img command is getting failed:
/usr/bin/python -m oslo_concurrency.prlimit --as=1073741824 --cpu=30 -- env LC_ALL=C LANG=C qemu-img info /opt/stack/data/nova/instances/_base/c252077f0b8f056ceb4e6069eb491d9876d487de.part --force-share" returned: 0

Environment:
============
Devstack: Queens
Network: Neutron
Hypervisor: Ubuntu1604 KVM
