In order to purge your DB from soft-deleted records, you need to move
the soft-deleted records from any table allowing them to the
corresponding shadow table so you could purge the shadow tables
eventually.

nova-manage db archive_deleted_rows is the command you're looking for.

Title:
  reservations table in nova mysql db grows constantly

Status in OpenStack Compute (nova):
  Invalid

Bug description:
  In case if there are large amount of VMs on OpenStack, we observer
  enormous growth of the nova.reservations table. The table is updated
  every 60 seconds, and soft-deleted records never deleted from the
  table. As a result this table could consume about 1/5 of space in
  /var/lib/mysql.
