This can be simplified to:

static int
esxDomainGetState(virDomainPtr domain, int *state, int *reason)
{
    int result = -1;
    esxPrivate *priv = domain->conn->privateData;
    esxVI_String *propertyNameList = NULL;
    esxVI_ObjectContent *virtualMachine = NULL;
    esxVI_VirtualMachinePowerState powerState;

    if (esxVI_EnsureSession(priv->primary) < 0) {
        return -1;
    }

    if (esxVI_String_AppendValueToList(&propertyNameList,
                                       "runtime.powerState") < 0 ||
        esxVI_LookupVirtualMachineByUuid(priv->primary, domain->uuid,
                                         propertyNameList, &virtualMachine,
                                         esxVI_Occurrence_RequiredItem) < 0 ||
        esxVI_GetVirtualMachinePowerState(virtualMachine, &powerState) < 0) {
        goto cleanup;
    }

    *state = esxVI_VirtualMachinePowerState_ConvertToLibvirt(powerState);

    if (reason) {
        *reason = 0;
    }

    result = 0;

  cleanup:
    esxVI_String_Free(&propertyNameList);
    esxVI_ObjectContent_Free(&virtualMachine);

    return result;
}
