Description of problem:
Core was generated by `/bin/qemu-img check $guest-img` when finished RHEL6.7 guest installation

Version-Release number of selected component (if applicable):
qemu-kvm-rhev-2.3.0-21.el7.x86_64
qemu-img-rhev-2.3.0-21.el7.x86_64
kernel-3.10.0-310.el7.x86_64

How reproducible:
1/5

Steps to Reproduce:
1.Create image by command: 
/bin/qemu-img create -f qcow2 /home/my_auto/autotest-devel/client/tests/virt/shared/data/images/rhel67-64-virtio.qcow2 20G

2.Install rhel6.7 guest in the image

3.After installation,check the image
Running '/bin/qemu-img check /home/my_auto/autotest-devel/client/tests/virt/shared/data/images/rhel67-64-virtio.qcow2'

Actual results:
Core was generated by `/bin/qemu-img check $guest-img`

Expected results:
