Bug 1372916

Description of problem: After deploying the overcloud, ssh keys and ifcfg files are zero btye when deploying in Ravello. This issue is not present with the ILT implementation. When this happens to compute1, if I remove the ifcfg-eth0 file and reboot, compute then receives the proper ifcfg-eth0 file. In the cloud-init log DataSourceConfigDriveNet points to /dev/vda1. This is the drive that is mounted and the data is copied to the controller when the image is transferred. When I mount /dev/vda1, the correct information for meta-data.json is there. The /etc/os-collect-config.conf has the proper meta-data url as well.



How reproducible:


Steps to Reproduce:
1. Deploy the overcloud 
 [stack@director ~]$ openstack overcloud deploy --templates ~/templates \
 --ntp-server 172.25.250.254 \
 --control-scale 1 --compute-scale 1 \
 --control-flavor control --compute-flavor compute \
 --neutron-tunnel-types vxlan --neutron-network-type vxlan \
 -e ~/templates/environments/network-isolation.yaml \
 -e ~/templates/network-environment.yaml
2. Attempt to SSH into the compute1 VM
3. Console into compute1 VM and CAT the ifcfg-eth0 file and the authorized_keys file.

Actual results:
Cannot SSH into the compute1 VM. After accessing the VM using the console, ifcfg-eth0 and authorized_keys are zero byte.

Expected results:
Access the compute1 VM using ssh. The ifcfg-eth0 and authorized_keys files are  populated correctly.
