Fixed In Version:	openstack-tripleo-heat-templates-0.8.11-1.el7ost	Doc Type:	Enhancement
Doc Text:	Feature: The "host" configuration setting in nova.conf and neutron.conf on compute nodes is now set to the fqdn of the compute node. Reason: In order for instance HA to function safely, the NovaCompute agent needs access to the name by which nova knows the current compute node. Neutron agents running on the compute nodes also need the equivalent value for their "host" configuration configured, otherwise instances can not be scheduled to the compute node. Result: The "host" configuration setting is now set to the fqdn of the compute node in /etc/nova/nova.conf and /etc/neutron/neutron.conf on each compute node deployed by OSP Director.

Description Andrew Beekhof 2015-12-08 03:11:53 UTC

Description of problem:

In order for instance HA to function safely, the NovaCompute agent needs access to the name by which nova knows the current compute node.

The code currently tries to obtain it on compute nodes with:

  openstack-config --get /etc/nova/nova.conf DEFAULT host

However this does not appear to be set/configured by director.

Could we either get it set here or have a pointer to a more appropriate location to obtain it?
