Public bug reported: Description ===========
As described in test_multi_nodes_isolate() in https://github.com/openstack/nova/blob/master/nova/tests/unit/virt/test_hardware.py#L3006-L3024, numa_fit_instance_to_host() function returns None for cpuset_reserved for cells with id >1. --------- def test_multi_nodes_isolate(self): host_topo = self._host_topology() inst_topo = objects.InstanceNUMATopology( emulator_threads_policy=( fields.CPUEmulatorThreadsPolicy.ISOLATE), cells=[objects.InstanceNUMACell( id=0, cpuset=set([0]), memory=2048, cpu_policy=fields.CPUAllocationPolicy.DEDICATED), objects.InstanceNUMACell( id=1, cpuset=set([1]), memory=2048, cpu_policy=fields.CPUAllocationPolicy.DEDICATED)]) inst_topo = hw.numa_fit_instance_to_host(host_topo, inst_topo) self.assertEqual({0: 0}, inst_topo.cells[0].cpu_pinning) self.assertEqual(set([1]), inst_topo.cells[0].cpuset_reserved) self.assertEqual({1: 2}, inst_topo.cells[1].cpu_pinning) self.assertIsNone(inst_topo.cells[1].cpuset_reserved) -------- However, we are testing libvirt driver with non-None value in https://github.com/openstack/nova/blob/master/nova/tests/unit/virt/libvirt/test_driver.py#L3052. This causes errors when deploying VMs with multi numa nodes with `cpu_thread_policy=isolate`. ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
