Openstack Installation problem. Why is my cirrOS instance always ending up in error state?

I am installing Openstack (havana) on dell PowerEdge R720 servers running ubuntu 12.04.3 and religiously following the install guide. Unfortunately, when I create a new instance (I am using the test cirrOS image), the instance ends up in error state. When I run "nova show cirrOS", the fault message shown is "{u'message': u'No valid host was found. ', u'code': 500, u'details': u' File "/usr/lib/python2.7/dist-packages/nova/scheduler/", line 107, in schedule_run_instance | | | raise exception.NoValidHost(reason="") " .

The log file "/var/log/nova/nova-scheduler.log" shows more details as follows:

"Error from last host: compute1 (node compute1): [u'Traceback (most recent call last):\n', u'  File "/usr/lib/python2.7/dist-packages/nova/compute/", line 1037, in _build_instance\n    set_access_ip=set_access_ip)\n', u'  File "/usr/lib/python2.7/dist-packages/nova/compute/", line 1410, in _spawn\n    LOG.exception(_(\'Instance failed to spawn\'), instance=instance)\n', u'  File "/usr/lib/python2.7/dist-packages/nova/compute/", line 1407, in _spawn\n    block_device_info)\n', u'  File "/usr/lib/python2.7/dist-packages/nova/virt/libvirt/", line 2070, in spawn\n    block_device_info, context=context)\n', u'  File "/usr/lib/python2.7/dist-packages/nova/virt/libvirt/", line 3205, in _create_domain_and_network\n    domain = self._create_domain(xml, instance=instance, power_on=power_on)\n', u'  File "/usr/lib/python2.7/dist-packages/nova/virt/libvirt/", line 3148, in _create_domain\n    domain.XMLDesc(0))\n', u'  File "/usr/lib/python2.7/dist-packages/nova/virt/libvirt/", line 3143, in _create_domain\n    domain.createWithFlags(launch_flags)\n', u'  File "/usr/lib/python2.7/dist-packages/eventlet/", line 179, in doit\n    result = proxy_call(self._autowrap, f, *args, **kwargs)\n', u'  File "/usr/lib/python2.7/dist-packages/eventlet/", line 139, in proxy_call\n    rv = execute(f,*args,**kwargs)\n', u'  File "/usr/lib/python2.7/dist-packages/eventlet/", line 77, in tworker\n    rv = meth(*args,**kwargs)\n', u'  File "/usr/lib/python2.7/dist-packages/", line 728, in createWithFlags\n    if ret == -1: raise libvirtError (\'virDomainCreateWithFlags() failed\', dom=self)\n', u"libvirtError: internal error: Process exited while reading console log output: char device redirected to /dev/pts/3\nCPU feature tsc-deadline not found\nCPU feature pcid not found\nqemu: could not load PC BIOS 'bios.bin'\n\n"] 2014-01-30 12:45:43.466 3098 WARNING nova.scheduler.driver [req-825a9f49-74eb-484f-9b81-9156f778d172 580f5ac495f24b5ba244e488aa92d730 4d874d7639c142eab658863028908d60] [instance: 6463aaf5-7ebb-4000-9e32-c793e31d0868] Setting instance to ERROR state."

I see qemu somewhere in that log but I am supposed to be using kvm.

What can I do next to successfully create instance?

May be a problem with your compute node configuration or libvirt problem. Can you post your /etc/nova/nova.conf and /etc/nova/nova-compute.conf (without password) ? :) Salvo.

Hi Salvo. I posted my response to your request as an answer because the text was too long for comment. Waiting for your further help. Thanks.

There are two log messages that seem to stand out.
1. /var/log/libvirt/libvirtd.log shows:

2. /var/log/nova/nova-compute.log shows:

Thanks Salvo for the response.

---Content of /etc/nova/nova-compute.conf is:


----Content of /etc/nova/nova.conf is:

root_helper=sudo nova-rootwrap /etc/nova/rootwrap.conf


rpc_backend = nova.rpc.impl_kombu

connection = mysql://nova:thepassword@controller/nova

---- Please note that I am using eth3 instead of eth1 because that's my hardware config.

Configure file seems ok. I think can be a problem with cpu of dell server. If you read log carefully there are at end a text "CPU feature tsc-deadline not found" and "could not load PC BIOS 'bios.bin'. Try with a ''cat /proc/cpuinfo'' and post result.
