hi all,<br><br>I installed openstack(Folsom) on ubuntu 12.04. Everythiong seems to be ok. instance can be started, but after sometime the instance will automatically stopped. <br><br>in the log:<br><b>DEBUG:nova.openstack.common.rpc.amqp:received</b> {u'_context_roles': [u'admin'], u'_context_request_id': u'req-035e4954-94fd-4050-bccf-4b87de89366a', ... ... u'_context_timestamp': u'2012-12-13T12:37:29.488625', u'_context_read_deleted': u'no', u'_context_user_id': None, <b>u'method': u'stop_instance'</b>, u'_context_remote_address': None}<br>

<br><br>what might be the problem? <br>3ks<br><br clear="all"><div>wei<br></div><br>
