Hey all, while strictly following the guidelines [1] on how to spawn an instance on the same host as another instance, I run into the error, that it cannot find some instanced called: "[", which - of course - is not the UUID I specified. I tried dropping the [ ] and just passed the UUID right away, but still, then is just takes the first character of the UUID and says, that it can't find this one.
my exact command line looked like this: nova boot --image 6c73d25e-df93-4c96-a803-9d419a367267 --flavor 16 --hint same_host=[df5fd16b-271d-45ac-9e9a-5d3ad33920e5] $instance_name 2012-06-26 08:26:28 ERROR nova.rpc.amqp [req-67363fee-1046-4ff8-90a2-05aacb1cbe10 fe655fd0ad49474db5882931685c77fe 8f956f17ce9d4c4d9957c230aab4f720] Exception during message handling 2012-06-26 08:26:28 TRACE nova.rpc.amqp Traceback (most recent call last): 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/rpc/amqp.py", line 252, in _process_data 2012-06-26 08:26:28 TRACE nova.rpc.amqp rval = node_func(context=ctxt, **node_args) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/scheduler/manager.py", line 115, in run_instance 2012-06-26 08:26:28 TRACE nova.rpc.amqp context, ex, *args, **kwargs) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/contextlib.py", line 24, in __exit__ 2012-06-26 08:26:28 TRACE nova.rpc.amqp self.gen.next() 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/scheduler/manager.py", line 105, in run_instance 2012-06-26 08:26:28 TRACE nova.rpc.amqp return self.driver.schedule_run_instance(*args, **kwargs) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/scheduler/multi.py", line 78, in schedule_run_instance 2012-06-26 08:26:28 TRACE nova.rpc.amqp return self.drivers['compute'].schedule_run_instance(*args, **kwargs) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/scheduler/filter_scheduler.py", line 72, in schedule_run_instance 2012-06-26 08:26:28 TRACE nova.rpc.amqp *args, **kwargs) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/scheduler/filter_scheduler.py", line 194, in _schedule 2012-06-26 08:26:28 TRACE nova.rpc.amqp filter_properties) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/scheduler/host_manager.py", line 218, in filter_hosts 2012-06-26 08:26:28 TRACE nova.rpc.amqp if host.passes_filters(filter_fns, filter_properties): 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/scheduler/host_manager.py", line 156, in passes_filters 2012-06-26 08:26:28 TRACE nova.rpc.amqp if not filter_fn(self, filter_properties): 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/scheduler/filters/affinity_filter.py", line 64, in host_passes 2012-06-26 08:26:28 TRACE nova.rpc.amqp if self._affinity_host(context, i) == me]) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/scheduler/filters/affinity_filter.py", line 30, in _affinity_host 2012-06-26 08:26:28 TRACE nova.rpc.amqp return self.compute_api.get(context, instance_id)['host'] 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/compute/api.py", line 1022, in get 2012-06-26 08:26:28 TRACE nova.rpc.amqp instance = self.db.instance_get(context, instance_id) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/db/api.py", line 540, in instance_get 2012-06-26 08:26:28 TRACE nova.rpc.amqp return IMPL.instance_get(context, instance_id) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/db/sqlalchemy/api.py", line 120, in wrapper 2012-06-26 08:26:28 TRACE nova.rpc.amqp return f(*args, **kwargs) 2012-06-26 08:26:28 TRACE nova.rpc.amqp File "/usr/lib/python2.7/dist-packages/nova/db/sqlalchemy/api.py", line 1339, in instance_get 2012-06-26 08:26:28 TRACE nova.rpc.amqp raise exception.InstanceNotFound(instance_id=instance_id) 2012-06-26 08:26:28 TRACE nova.rpc.amqp InstanceNotFound: Instance [ could not be found. And that's the error in the log then. Any ideas if it's my fault or how to work around this? Many thanks in advance, Christian Parpart.
