I suggest that you check the status of nova compute service

openstack compute service list

If compute service is up and healthy, check the nova compute logs for
any possible error there.

sudo journalctl -u devstack@n-cpu

Hi Sam,
 
I tried all the option of the config ( ODL oxygen and Devstack Queens )
and now build is successful.  But when I create VM , it gives error
“Message No valid host was found”.
 
http://paste.openstack.org/show/722324/
 
 
I run the below command  and error came from the last command.
 
nova keypair-add --pub-key ~/.ssh/id_rsa.pub admin_key
nova keypair-list
neutron net-create vx-net0 --provider:network_type vxlan --
provider:segmentation_id 1500
neutron subnet-create vx-net0 20.0.0.0/24 --name vx-subnet0 --dns-
nameserver 8.8.8.8
neutron port-create vx-net0 --fixed-ip subnet_id=$(neutron subnet-list
| grep -w vx-subnet0 | awk '{print $2}'),ip_address=20.0.0.3 --name P1
openstack server create --flavor m1.nano --image cirros-0.3.5-x86_64-

carbon is old as is nitrogen, so I would go with oxygen. You only need
a couple features: odl-infrautils-ready and odl-netvirt-sfc. You can
see the features used in the karaf log for the job:

This is all old stuff. EVerything needed is now in the odl-netvirt-sfc
feature.

dlux is flaky. deprecated in fluorine.

l2switch should not be loaded with odl-netvirt-sfc - it will cause
problems. You don't need any of this stuff for sfc.

This is the only feature you really need . This feature will pull in
all the netvirt, openflowplugin, genius, neutron, etc features that are
required. It will
not pull in any dlux.
