sha1 Nova at: 106fb458c7ac3cc17bb42d1b83ec3f4fa8284e71
sha1 ironic at: 036c79e38f994121022a69a0bc76917e0048fd63

The ironic driver passes stats to nova's resource tracker in
get_available_resources(). Sometimes these appear to get through to the
database without modification, sometimes they seem to be replaced
entirely by other stats generated by the resource tracker. The correct
behaviour should be to combine the two.

As an example, the following query on the compute_nodes table in nova's
database shows the contents for a tripleo system (all nodes are ironic):

mysql> select hypervisor_hostname, stats from compute_nodes;

The nodes with ironic stats have not had any instances created on them,
the ones with resource tracker stats but no ironic stats have instances
on them. This is shown by the following:

Title:
  Resource tracker should report virt driver stats

Status in OpenStack Compute (Nova):

Bug description:
  sha1 Nova at: 106fb458c7ac3cc17bb42d1b83ec3f4fa8284e71

  The ironic driver passes stats to nova's resource tracker in
  get_available_resources(). Sometimes these appear to get through to
  the database without modification, sometimes they seem to be replaced
  entirely by other stats generated by the resource tracker. The correct
  behaviour should be to combine the two.

  As an example, the following query on the compute_nodes table in
  nova's database shows the contents for a tripleo system (all nodes are
  ironic):
