Frank,
Can you please provide the output of:
nova host-list
As well as link to a paste bin of relevant /var/log/nova/*.log files
from both the nova controller, scheduler, as well as any hypervisors?
This will give us a good starting point.
Regards,
Richard

Hi all,
When I try to launch an instance using command:
"nova boot --flavor 2 --image 575623a9-fcbe-4925-86c0-0042d2cb9745
test-nova"
I get the following message:
fault | {"message": "No valid host was
found. There are not enough hosts available.", "code": 500, "details":
" File \"/opt/stack/nova/nova/conductor/manager.py\", line 614, in
build_instances
when I look at the log produced by nova-schedule, I can see:
2014-11-03 10:29:11.301 INFO nova.filters
[req-c811049f-c670-4205-9436-a812a048d2f9 admin admin] Filter

2014-11-03 10:29:11.301 DEBUG nova.scheduler.filter_scheduler
[req-c811049f-c670-4205-9436-a812a048d2f9 admin admin] There are 0
hosts available but 1 instances requested to build. from (pid=17646)
select_destinations /opt/stack/nova/nova/scheduler/filter_scheduler.py:157
It seems that openstack controller can't recognize my host. BTW, my
host has enough resources, such as memory, cpu, disk and so on.
I have no idea now, any help will be appreciated.
