Public bug reported: https://github.com/openstack/nova/blob/master/nova/scheduler/host_manager.py#L674-L718
In _get_host_states, a list of all computes nodes is retrieved with a `state_key` of `(host, node)`. https://github.com/openstack/nova/blob/master/nova/scheduler/host_manager.py#L692 https://github.com/openstack/nova/blob/master/nova/scheduler/host_manager.py#L708 The small piece of code here removes all of the dead compute nodes from host_state_map https://github.com/openstack/nova/blob/master/nova/scheduler/host_manager.py#L708 However, the result is returned by iterating over all seen nodes and using that index for host_state_map, some of which have been deleted by the code above, resulting in a KeyError. https://github.com/openstack/nova/blob/master/nova/scheduler/host_manager.py#L718 ** Affects: nova Importance: Undecided Status: New ** Tags: scheduler -- You received this bug notification because you are a member of Yahoo!
