Title:
  resource tracker reporting strange values in AUDIT logs

Status in OpenStack Compute (Nova):
  Invalid
Status in OpenStack Compute (nova) folsom series:
  Fix Released

Bug description:
  I'm running Folsom on Ubuntu 12.04. I have one controller running API
  and scheduler and a compute node running network and compute. Multi
  host is turned on.

  Here's a collection of some AUDIT outputs when launching VMs:

  Something is not right in the reporting of memory. A second issue in
  the resource tracker is that I get the following

  2012-12-20 16:44:40 AUDIT nova.compute.resource_tracker [req-
  6608e127-c615-4647-926d-9f8e24f33cad 545de9518b724f069b410513614bda24
  71f58bddf33b4a0f8bd877bf87c8a2ae] Disk limit not specified, defaulting
  to unlimited

  despite having 
  reserved_host_disk_mb=5000

  In the nova.conf on all nodes (unless I'm mistaken and this is not the
  correct flag)

  It seems like this is expected to be put into filter_properties by the
  scheduler, though I can't see anywhere in the scheduler that would do
  that.
