<div dir="ltr">Hello everyone,<br><br>I am trying to run DevStack on Ubuntu 14.04 in a single 
VirtualBox. An <br>error turns up  before it successfully starts. Yesterday I clarified this <br>question not  clearly enough，so I make a supplication for it. My steps 
are:<br>1), Git clone DevStack,<br>2), Copy devstack/local.conf.sample to 
DevStack folder and rename it to<br>local.conf.<br><br>the finished steps before the error turns up are listed as follows:<br><br>2016-06-29 09:11:53.081 | stack.sh log /opt/stack/logs/stack.sh.log.2016-06-29-171152<br>2016-06-29 09:12:19.797 | Installing package prerequisites<br>2016-06-29 09:15:27.224 | Installing OpenStack project source<br>2016-06-29 09:24:43.323 | Installing Tricircle<br>2016-06-29 09:24:55.979 | Starting RabbitMQ<br>2016-06-29 09:25:00.731 | Configuring and starting MySQL<br>2016-06-29 09:25:20.143 | Starting Keystone<br>2016-06-29 09:43:18.591 | Configuring Glance<br>2016-06-29 09:43:59.667 | Configuring Neutron<br>2016-06-29 09:46:30.646 | Configuring Cinder<br>2016-06-29 09:46:54.719 | Configuring Nova<br>2016-06-29 09:48:23.175 | Configuring Tricircle<br>2016-06-29 09:51:24.143 | Starting Glance<br>2016-06-29 09:52:11.133 | Uploading images<br>2016-06-29 09:52:45.460 | Starting Nova API<br>2016-06-29 09:53:27.511 | Starting Neutron<br>2016-06-29 09:54:21.476 | Creating initial neutron network elements<br><br>The last errors when it stops running are:<br><br>Request body: {u'network': {u'router:external': True, u'provider:network_type': u'flat', u'name': u'public', u'provider:physical_network': u'public', u'admin_state_up': True}}^[[00m ^[[00;33mfrom (pid=29980) prepare_request_body /opt/stack/neutron/neutron/api/v2/base.py:674^[[00m<br>2016-06-29 17:56:04.359 ^[[00;32mDEBUG neutron.db.quota.driver [^[[01;36mreq-e97f6276-8e19-408b-829a-004a31256453 ^[[00;36madmin 13869ba8005b480bbcbe17b2695fd5e2^[[00;32m] ^[[01;35m^[[00;32mResources subnetpool have unlimited quota limit. It is not required to calculate headroom ^[[00m ^[[00;33mfrom (pid=29980) make_reservation /opt/stack/neutron/neutron/db/quota/driver.py:191^[[00m<br>2016-06-29 17:56:04.381 ^[[00;32mDEBUG neutron.db.quota.driver [^[[01;36mreq-e97f6276-8e19-408b-829a-004a31256453 ^[[00;36madmin 13869ba8005b480bbcbe17b2695fd5e2^[[00;32m] ^[[01;35m^[[00;32mAttempting to reserve 1 items for resource network. Total usage: 0; quota limit: 10; headroom:10^[[00m ^[[00;33mfrom (pid=29980) make_reservation /opt/stack/neutron/neutron/db/quota/driver.py:223^[[00m<br>2016-06-29 17:56:04.425 ^[[01;31mERROR neutron.api.v2.resource [^[[01;36mreq-e97f6276-8e19-408b-829a-004a31256453 ^[[00;36madmin 13869ba8005b480bbcbe17b2695fd5e2^[[01;31m] ^[[01;35m^[[01;31mcreate failed^[[00m<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00mTraceback (most recent call last):<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m  File "/opt/stack/neutron/neutron/api/v2/resource.py", line 78, in resource<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m    result = method(request=request, **args)<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m  File "/opt/stack/neutron/neutron/api/v2/base.py", line 424, in create<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m    return self._create(request, body, **kwargs)<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m  File "/usr/local/lib/python2.7/dist-packages/oslo_db/api.py", line 148, in wrapper<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m    ectxt.value = e.inner_exc<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m  File "/usr/local/lib/python2.7/dist-packages/oslo_utils/excutils.py", line 221, in __exit__<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m    self.force_reraise()<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m  File "/usr/local/lib/python2.7/dist-packages/oslo_utils/excutils.py", line 197, in force_reraise<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m    six.reraise(self.type_, self.value, self.tb)<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m  File "/usr/local/lib/python2.7/dist-packages/oslo_db/api.py", line 138, in wrapper<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m    return f(*args, **kwargs)<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m  File "/opt/stack/neutron/neutron/api/v2/base.py", line 535, in _create<br>[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m    return obj_creator(request.context, **kwargs)<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m  File "/opt/stack/tricircle/tricircle/network/plugin.py", line 238, in create_network<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m    is_external = self._ensure_az_set_for_external_network(net_data)<br>^[[01;31m2016-06-29 17:56:04.425 TRACE neutron.api.v2.resource ^[[01;35m^[[00m  File "/opt/stack/tricircle/tricircle/network/plugin.py", line 184, in _ensure_az_set_for_external_network<br
