>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>          Components: KVM
>    Affects Versions: 4.2.0, Future, 4.3.0, 4.4.0
>            Reporter: Wido den Hollander

>             Fix For: 4.4.0
> 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.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.
