Hi, I'm new to openstack. I deployed an openstack environment with nova-network, nova compute, horizon, glance and all of its dependencies to run. All the integration of this components runs well. The error is when I try to create an instance based on cirros-0.3.3-x86_64 image. The openstack version that I'm using is Juno with Debian Jessie. When the instance launch the Horizon and nova-compute logs display the same error: Message Remote error: UnicodeDecodeError 'ascii' codec can't decode byte 0xc3 in position 673: ordinal not in range(128) [u'Traceback (most recent call last):\n', u' File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/dispatcher.py", line 133, in _dispatch Code 500 Details File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 290, in decorated_function return function(self, context, *args, **kwargs) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 2111, in run_instance do_run_instance() File "/usr/lib/python2.7/dist-packages/nova/openstack/common/lockutils.py", line 249, in inner return f(*args, **kwargs) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 2110, in do_run_instance legacy_bdm_in_spec) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 1224, in _run_instance notify("error", fault=e) # notify that build failed File "/usr/lib/python2.7/dist-packages/nova/openstack/common/excutils.py", line 68, in __exit__ six.reraise(self.type_, self.value, self.tb) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 1208, in _run_instance instance, image_meta, legacy_bdm_in_spec) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 1372, in _build_instance filter_properties, bdms, legacy_bdm_in_spec) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 1418, in _reschedule_or_error self._log_original_error(exc_info, instance_uuid) File "/usr/lib/python2.7/dist-packages/nova/openstack/common/excutils.py", line 68, in __exit__ six.reraise(self.type_, self.value, self.tb) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 1413, in _reschedule_or_error bdms, requested_networks) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 2158, in _shutdown_instance self._try_deallocate_network(context, instance, requested_networks) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 2122, in _try_deallocate_network self._set_instance_error_state(context, instance['uuid']) File "/usr/lib/python2.7/dist-packages/nova/openstack/common/excutils.py", line 68, in __exit__ six.reraise(self.type_, self.value, self.tb) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 2117, in _try_deallocate_network self._deallocate_network(context, instance, requested_networks) File "/usr/lib/python2.7/dist-packages/nova/compute/manager.py", line 1792, in _deallocate_network context, instance, requested_networks=requested_networks) File "/usr/lib/python2.7/dist-packages/nova/network/api.py", line 101, in wrapped return func(self, context, *args, **kwargs) File "/usr/lib/python2.7/dist-packages/nova/network/api.py", line 351, in deallocate_for_instance requested_networks=requested_networks) File "/usr/lib/python2.7/dist-packages/nova/network/rpcapi.py", line 190, in deallocate_for_instance return cctxt.call(ctxt, 'deallocate_for_instance', **kwargs) File "/usr/lib/python2.7/dist-packages/oslo/messaging/rpc/client.py", line 150, in call wait_for_reply=True, timeout=timeout) File "/usr/lib/python2.7/dist-packages/oslo/messaging/transport.py", line 90, in _send timeout=timeout) File "/usr/lib/python2.7/dist-packages/oslo/messaging/_drivers/amqpdriver.py", line 412, in send return self._send(target, ctxt, message, wait_for_reply, timeout) File "/usr/lib/python2.7/dist-packages/oslo/messaging/_drivers/amqpdriver.py", line 405, in _send raise result This is my locale on physical servers: LANG="es_ES.UTF-8" Debian operating system is configured in spanish.
