[Bug 1672792] [NEW] Nova with ceph backend instance creation fails with: the name of the pool must be a string
Public bug reported:
Situation: Ocata (RDO), Nova configured with ceph backend as follows:
[libvirt]
images_type = rbd
images_rbd_pool = nova
images_rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_user = nova_cinder
rbd_secret_uuid = <uuid>
When launching an image backed instance (so not backed by a cinder
volume), instance creation fails with: 'the name of the pool must be a
string'.
After some digging I found that in: /usr/lib/python2.7/site-
packages/nova/virt/libvirt/storage/rbd_utils.py in _connect_to_rados in
the call ioctx = client.open_ioctx(pool_to_open)
pool_to_open is passed as unicode and in /usr/lib/python2.7/site-
packages/rados.py a check is done which fails if ioctx_name is not a
string.
Easy fix seems to be to do a cast to string in _connect_to_rados:
ioctx = client.open_ioctx(str(pool_to_open))
This fixes the issue for me.
Creating an instance with a ceph backed volume is not affected by this
issue, this works fine.

images_rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_user = nova_cinder
rbd_secret_uuid = <uuid>
When launching an image backed instance (so not backed by a cinder
volume), instance creation fails with: 'the name of the pool must be a
string'.
After some digging I found that in: /usr/lib/python2.7/site-
packages/nova/virt/libvirt/storage/rbd_utils.py in _connect_to_rados
in the call ioctx = client.open_ioctx(pool_to_open)
pool_to_open is passed as unicode and in /usr/lib/python2.7/site-
packages/rados.py a check is done which fails if ioctx_name is not a
string.
Easy fix seems to be to do a cast to string in _connect_to_rados:
ioctx = client.open_ioctx(str(pool_to_open))
This fixes the issue for me.
Creating an instance with a ceph backed volume is not affected by this
issue, this works fine.
