1. Create new environment (CentOS, simple mode)
2. Choose GRE neutron
3. Choose Ceph for volumes
4. Add 1 controller+ceph, 1 compute, 1 ceph
5. Start deployment. It was successful
6. Upload image F17-x86_64-cfntools.qcow2
7. Start OSTF test "Check stack autoscaling"
8. Test has failed with on step 13 with error: ssh -o StrictHostKeyChecking=no -i /tmp/tmp.oUJrOm8DRM ec2-user@172.16.0.132 kill -9 847 command failed
