> Components: KVM
> Affects Versions: 4.2.0, Future, 4.3.0, 4.4.0
> Reporter: Wido den Hollander

>
> When libvirt lost the RBD storage pool, could be due to a libvirt restart,
> the KVM Agent will re-create the storage pool.
> When doing so the createStoragePool() method in LibvirtStoragePoolAdapter
> doesn't return a properly filled LibvirtStoragePool object.
> This can lead to situations where the agent for example tries to delete a
> volume, but that fails:
> "Unprotecting and Removing RBD snapshots of image
> null/7a3bdc9f-5cd3-4192-a814-18acf561f0d0 prior to removing the image
> Failed to delete volume: com.cloud.utils.exception.CloudRuntimeException:
> com.ceph.rados.RadosException: Could not set configuration option key (-22)"
> Notice the "null" in the first line, it's because this information is not
> properly filled in the returned object.
