  Though openstack volume list says it's in use by this vm as vdb,
  lsblock on the vm looks like:

  # lsblk
  NAME   MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
  vda    253:0    0  40G  0 disk
  └─vda1 253:1    0  40G  0 part /

  Libvirt pieces of the log that points the id of the volume will be
  attached soon.

  Thanks!

  José.
