Hi,
You need configure libvirt to use Ceph as its backend.
Put this config to [libvirt] in nova.conf:
[libvirt]
inject_partition=-2
inject_password = false
live_migration_flag=VIR_MIGRATE_UNDEFINE_SOURCE,VIR_MIGRATE_PEER2PEER,VIR_MIGRATE_LIVE,VIR_MIGRATE_PERSIST_DEST
inject_key=False
images_type = rbd
images_rbd_pool = [ceph vms pool]
images_rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_user = cinder
rbd_secret_uuid = [Ceph FSID]
disk_cachemodes="network=writeback"
hw_disk_discard = unmap

Hi
I think that this problem has already been reported, but I don't get clearly how to resolve it.
I have an openstack deployment with some compute nodes. The OS deployment is configured to use a ceph cluster (cinder+glance+nova ephemeral)
My problem is this: the OS hypervisor stats reports the compute local HDD free space/used space instead of Ceph usage. At the end, I cannot create new VM because Nova reports that there's no space left in any compute node, while I have a lot space in ceph cluster....
I have OS Juno + Ceph Firefly.
thanks in advance.
