oci compute capacity report is not correct in which ad has status AVAILABLE

When I run an availability report on my ADs I seem to be getting incorrect information.

It reports that US-CHICAGO-1-AD-3 is AVAILABLE and US-CHICAGO-1-AD-2 is OUT_OF_HOST_CAPACITY, but the reverse is actually true.

When creating instances of the same shape and shape-availabilities I can create instances in US-CHICAGO-1-AD-2 but not in US-CHICAGO-1-AD-3.

Below are the commands and results that show that the tool is reporting incorrect availability.

oci compute compute-capacity-report create --availability-domain QrSF:US-CHICAGO-1-AD-3 --compartment-id \
redacted \
--shape-availabilities '[{\"instanceShape\":\"VM.Standard.A1.Flex\",\"instanceShapeConfig\":{\"memoryInGBs\":6,\"ocpus\":1}}]'

{
  "data": {
    "availability-domain": "QrSF:US-CHICAGO-1-AD-3",
    "compartment-id": "redacted",
    "shape-availabilities": [
      {
        "availability-status": "AVAILABLE",
        "available-count": null,
        "fault-domain": null,
        "instance-shape": "VM.Standard.A1.Flex",
        "instance-shape-config": {
          "memory-in-gbs": 6.0,
          "nvmes": null,
          "ocpus": 1.0
        }
      }
    ],
    "time-created": "2024-02-05T20:38:50.116000+00:00"
  }

oci compute compute-capacity-report create --availability-domain QrSF:US-CHICAGO-1-AD-2 \
--compartment-id redacted --shape-availabilities \'[{\"instanceShape\":\"VM.Standard.A1.Flex\",\"instanceShapeConfig\":{\"memoryInGBs\":6,\"ocpus\":1}}]'

{
  "data": {
    "availability-domain": "QrSF:US-CHICAGO-1-AD-2",
    "compartment-id": "redacted",
    "shape-availabilities": [
      {
        "availability-status": "OUT_OF_HOST_CAPACITY",
        "available-count": null,
        "fault-domain": null,
        "instance-shape": "VM.Standard.A1.Flex",
        "instance-shape-config": {
          "memory-in-gbs": 6.0,
          "nvmes": null,
          "ocpus": 1.0
        }
      }
    ],
    "time-created": "2024-02-05T20:39:12.799000+00:00"
  }
}

Start by rerunning the two oci compute compute-capacity-report create commands for US-CHICAGO-1-AD-2 and AD-3 with the reported shape configuration, then compare the results with actual instance-creation behavior. Done means the availability report consistently identifies which availability domain can host the requested VM.Standard.A1.Flex shape.
