can't launch instance using ceph without authentication

[cristi1979]

Instance fails when using ceph as a storage backend.

The main complain comes from "/usr/lib/python2.7/site-packages/nova/virt/libvirt/config.py", line 527.

Putting a print bedore "if self.auth_secret_type is not None:" shows that the code is hit twice, first with auth_secret_type=cepg, second time with auth_secret_type=None.

We fixed it in our side by commenting the entire if statement.

[Sean Dague (sdague)]

Looks like a roadmap of synchronizing the code as listed in the bug is given

[Sujitha (sujitha-neti)]

I'm not able to reproduce the bug. I installed devstack with ceph as storage backend. Tried to create instance using nova boot. Its working as expected.
