Python estimate_instance_overhead Exemples

Exemple #1

    def test_overhead(self):
        driver = self._get_driver()
        instance = {'memory_mb': 30720, 'vcpus': 4}

        # expected memory overhead per:
        # https://wiki.openstack.org/wiki/XenServer/Overhead
        expected = ((instance['memory_mb'] * xenapi_driver.OVERHEAD_PER_MB) +
                    (instance['vcpus'] * xenapi_driver.OVERHEAD_PER_VCPU) +
                    xenapi_driver.OVERHEAD_BASE)
        expected = math.ceil(expected)
        overhead = driver.estimate_instance_overhead(instance)
        self.assertEqual(expected, overhead['memory_mb'])
