Title:
  Block live migration fails when vm is being used

Status in OpenStack Compute (nova):
  Expired

Bug description:
  Block live migration unexpectedly fails when the vm to be migrated has
  some memory usage.

  This error occurred to me with a Sahara cluster. The steps are:

  1 - Create a cluster
  2 - Migrating one VM of this idle cluster is ok
  3 - Launch a wordcount job on the cluster
  4 - From a given time of the job (where the ram is dirtier), trying to migrate this same VM fails.

  My problem occurred with a specific job, but I think it may occur in
  any memory-bound process.
