File injection doesn't work with Ceph

Env: MOS 6.1 (build 525 RC3) Ubuntu - HA - Neutron VLAN
3 controllers, 2 compute with Ceph for volumes/images/ephemeral volumes

Steps to reproduce:

1. Prepare settings on compute nodes because of bug https://bugs.launchpad.net/fuel/+bug/1467579

compute:
# install python-guestfs and python-guestfs
apt-get install libguestfs-tools

# set inject_partition=-1
root@node-4:~# grep '^inject_partition' /etc/nova/nova.conf
inject_partition=-1

# set permissions for kernel
chmod 644 /boot/vmlinuz-3.13.0-55-generic

# restart compute service
service nova-compute restart

# run test
libguestfs-test-tool

2. Create instance with metadata

neutron net-list
nova boot --flavor m1.micro --image TestVM --meta key555=val555 --nic net-id=944808e4-300c-40e3-8cd1-404a89df04ec test3453

3. Ssh to instance and verify /meta.js

ip netns exec qdhcp-944808e4-300c-40e3-8cd1-404a89df04ec ssh cirros@192.168.111.8
cat /meta.js

Expected result:

Metadata arrive into instance in "/meta.js" file

Actual result:

root@node-1:~# ip netns exec qdhcp-944808e4-300c-40e3-8cd1-404a89df04ec ssh cirros@192.168.111.8
