SUMMARY

It is observed on KVM environments that the capacity metrics displayed on the UI show the allocated value and total for CPU and Memory, however the UI is displayed the used value instead of the allocated value

Example API response for listCapacity API:

{
                "type": 0,
                "name": "MEMORY",
                "zoneid": "a3cc5e82-56a3-4a48-96c1-b087146b2afc",
                "zonename": "NVS Home Zone",
                "capacityallocated": 21340618752,
                "capacityused": 8321499136,
                "capacitytotal": 32445620224,
                "percentused": "25.65"
            },
            {
                "type": 1,
                "name": "CPU",
                "zoneid": "a3cc5e82-56a3-4a48-96c1-b087146b2afc",
                "zonename": "NVS Home Zone",
                "capacityallocated": 32000,
                "capacityused": 16500,
                "capacitytotal": 67200,
                "percentused": "24.55"
            },

Example in the UI:

Check that values displayed as CPU Allocated and Memory Allocated are actually CPU used and Memory used (as well as the calculated percentage)

STEPS TO REPRODUCE

	List zone metrics, or host metrics

EXPECTED RESULTS

CPU and Memory Allocated values

ACTUAL RESULTS

CPU and Memory Used values
