Hi, Alberto, I'm really interested in your proposal, have you already submitted your spec? or is there any topic for you to have a discussion with Nova team in design summit?
I wonder what if the nova compute host use shared storage backend, like NFS or Ceph? I have another suggestion, we can consider adding this capability in nova manage CLI, since it's just may be used by operator or administrator(at least for create/update/delete command), right?
