Public bug reported:
OpenStack Pike.
I create more than one instances on the dashboard. The nova-scheduler will
revice a argument named spec_obj.
select_destinations(self, ctxt,request_spec=None,
filter_properties=None,spec_obj=_sentinel, instance_uuids=None)
spec_obj has a attribute named instance_uuid, the attribute will be used
in GroupAntiAffinityFilter class.
class _GroupAntiAffinityFilter(filters.BaseHostFilter):
"""Schedule the instance on a different host from a set of group
hosts.
"""
RUN_ON_REBUILD = False
def host_passes(self, host_state, spec_obj):
# Only invoke the filter if 'anti-affinity' is configured
policies = (spec_obj.instance_group.policies
if spec_obj.instance_group else [])
if self.policy_name not in policies:
return True
# NOTE(hanrong): Move operations like resize can check the same source
# compute node where the instance is. That case, AntiAffinityFilter
# must not return the source as a non-possible destination.
if spec_obj.instance_uuid in host_state.instances.keys():
return True
group_hosts = (spec_obj.instance_group.hosts
if spec_obj.instance_group else [])
LOG.debug("Group anti affinity: check if %(host)s not "
"in %(configured)s", {'host': host_state.host,
'configured': group_hosts})
if group_hosts:
return host_state.host not in group_hosts
# No groups configured
return True
When I create more than one instances, spec_obj.instance_uuid is always
the same.
