I can get ephemeral storage for Nova to work with RBD backend, but I don't understand why it only works with the admin cephx user? With a different user starting a VM fails, even if I set its caps to 'allow *'. Here's what I have in nova.conf: libvirt_images_type=rbd libvirt_images_rbd_pool=images rbd_secret_uuid=fd9a11cc-6995-10d7-feb4-d338d73a4399 rbd_user=images The secret UUID is defined following the same steps as for Cinder and Glance: http://ceph.com/docs/master/rbd/libvirt/ BTW rbd_user option doesn't seem to be documented anywhere, is that a documentation bug? And here's what 'ceph auth list' tells me about my cephx users: client.admin key: AQCoSX1SmIo0AxAAnz3NffHCMZxyvpz65vgRDg== caps: [mds] allow caps: [mon] allow * caps: [osd] allow * client.images key: AQC1hYJS0LQhDhAAn51jxI2XhMaLDSmssKjK+g== caps: [mds] allow caps: [mon] allow * caps: [osd] allow * client.volumes key: AQALSn1ScKruMhAAeSETeatPLxTOVdMIt10uRg== caps: [mon] allow r caps: [osd] allow class-read object_prefix rbd_children, allow rwx pool=volumes, allow rx pool=images Setting rbd_user to images or volumes doesn't work. What am I missing?
