Public bug reported:

Description of problem:
Openstack on rhel 7.0 VM box
rhos 5.0  version .

After creating instance , we try to attach volume to it .
The volume created by tempest code :
def test_attach_detach_volume_to_instance(self):
        # Volume is attached and detached successfully from an instance
        mountpoint = '/dev/vdc'
        _, body = self.client.attach_volume(self.volume['id'],
                                            self.server['id'],
                                            mountpoint)

After volume has been created , we are attaching it to instance .
The result of this action is that cinder shows that the volume attached to instance .
But in nova - instace we do not see the volume in lsblk output  .
We get error from logs :
/var/log/nova/nova-compute.log:136:2014-09-08 02:59:39.573 31416 DEBUG nova.virt.disk.api [req-c0039d74-1c31-4e19-8719-bf3fb8eca505 8826f60585d244339c6a51dd7ce7b26f fbf97ed492214e9b8bb9f47206879a9c] Unable to mount image /var/lib/nova/instances/5531d5a9-cefd-4873-bbca-bdd4336ca5a8/disk with error Error mounting /var/lib/nova/instances/5531d5a9-cefd-4873-bbca-bdd4336ca5a8/disk with libguestfs (mount_options: /dev/sda on / (options: ''): mount: /dev/sda is write-protected, mounting read-only


I attached another volume with auto mount  point .
When we delete the instacne the cinder is binded to deleted instance and we can not delete the volume.

How reproducible:

#1 Create instance  
#2 create volume with tempest code based on : 
def test_attach_detach_volume_to_instance(self):
        # Volume is attached and detached successfully from an instance
        mountpoint = '/dev/vdc'
        _, body = self.client.attach_volume(self.volume['id'],
                                            self.server['id'],
                                            mountpoint)
#2 the volume is attached , but we dont see it in instance (cirros image)
#3 attach another volume with auto mount point to instance
#4 delete the instance 
#5 at this point cinder attachment is to "not existing" instance and we are not able to delete the volume.
