Jin, I didn't see that you had opened a new review and abandoned the
original. In the future, please update your existing review instead of
creating new reviews.

Another note, as you have probably seen in the code, it appears that
memory and disk are returned for scheduling periodically when an
instance is suspended, however vcpus are not.

Title:
  Resource usage will not be updated when suspending instance

Status in OpenStack Compute (Nova):
  In Progress
Status in OpenStack Manuals:
  Fix Released

Bug description:
  Suspending instance will not update resource usage.

  Instance suspending should move all contents in the ram to hard disk.
  Then vcpu and used memory should be decreased and hard disk useage should be increased.
  However it didn't happen.

  This will lead to trouble in the following scenario:
  When the memory of all compute nodes are exhaust, to create a new instance, it's useless to suspend some alive instances, but have to delete them.
