Hello Ling,

1. Please check whether baremetal compute's hostname is correct:
"Host = node1"? Is this same to the hostname in the result of "nova service-list"?

2. Please check resource_track and capability information are being sent properly between compute and scheduler:

verbose = True
debug = True

/var/log/nova/compute.log
...
nova.compute.resource_tracker [-] Free ram (MB): xxx
nova.compute.resource_tracker [-] Free disk (GB): xxx
nova.compute.resource_tracker [-] Free VCPUS: xx

nova.compute.resource_tracker [-] Compute_service record updated for node1:xxx
...

/var/log/nova/scheduler.log
...
nova.scheduler.host_manager [req-xxx None None] Received compute service update from (u'node1', u'xxx'). update_service_capabilities /usr/lib/python2.6/site-packages/nova/scheduler/host_manager.py:359

nova.openstack.common.rpc.amqp [-] received {... u'host': u'node1', u'capabilities': [{... , u'host': u'node1', ...} _safe_log /usr/lib/python2.6/site-packages/nova/openstack/common/rpc/common.py:276
...

3. Please try cpu_arch="s== x86_64" when setting a baremetal flavor.

Thanks,
Mikyung

Subject: [openstack-dev] [nova][baremetal] Error when running nova boot for	baremetal node


Hi, 
I have installed openstack Grizzly release and trying to set up to deploy baremetal nodes. I am following the instructions from https://wiki.openstack.org/wiki/Baremetal The controller and the compute hosts are two separate nodes. 

The last step failed. 
~#nova boot --flavor my-baremetal-flavor --image my-image my-baremetal-node 
~#nova show my-baremetal-node 
... 
| fault | {u'message': u'NoValidHost', u'code': 500, u'details': u'No valid host was found. | 



Here are some related date, I have substituted the ip/password and and mac with fake ones. 
~# nova baremetal-node-list

On compute host node1, the /etc/nova/nova.conf looks like this
