Hi, I Have encountered a problem and maybe someone can help (RHEL-6.4 with upstream devstack). I deploy a VM and it works. If I restart my host, install devstack and then try and deploy a VM then it fails. If I try again it works. After the next reboot in order to get a VM up and running I need to deploy 3 VM's. The trace on nova compute is: 2013-05-16 08:18:11.742 ERROR nova.openstack.common.rpc.amqp [req-cd75ed38-1d04-4611-9f34-cce01b388413 demo demo] Exception during message handling 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp Traceback (most recent call last): 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/openstack/common/rpc/amqp.py", line 433, in _process_data 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp **args) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/openstack/common/rpc/dispatcher.py", line 148, in dispatch 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp return getattr(proxyobj, method)(ctxt, **kwargs) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/exception.py", line 98, in wrapped 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp temp_level, payload) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/usr/lib64/python2.6/contextlib.py", line 23, in __exit__ 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp self.gen.next() 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/exception.py", line 75, in wrapped 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp return f(self, context, *args, **kw) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/compute/manager.py", line 213, in decorated_function 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp pass 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/usr/lib64/python2.6/contextlib.py", line 23, in __exit__ 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp self.gen.next() 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/compute/manager.py", line 199, in decorated_function 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp return function(self, context, *args, **kwargs) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/compute/manager.py", line 264, in decorated_function 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp function(self, context, *args, **kwargs) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/compute/manager.py", line 241, in decorated_function 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp e, sys.exc_info()) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/usr/lib64/python2.6/contextlib.py", line 23, in __exit__ 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp self.gen.next() 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/compute/manager.py", line 228, in decorated_function 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp return function(self, context, *args, **kwargs) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/compute/manager.py", line 1320, in run_instance 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp do_run_instance() 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/openstack/common/lockutils.py", line 246, in inner 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp retval = f(*args, **kwargs) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/compute/manager.py", line 1319, in do_run_instance 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp admin_password, is_first_time, node, instance) 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp File "/opt/stack/nova/nova/compute/manager.py", line 877, in _run_instance 2013-05-16 08:18:11.742 TRACE nova.openstack.common.rpc.amqp notify("error", msg=unicode(e)) #

Problem is that I am unable to delete any of these. Any ideas? Thanks Gary
