Hi Laurent, I resolved my issues and I could create new vm's.Thanks for your help. Now I have some doubt in different network types Vlan,Vxlan and flat networks. How these networks helps in openstack.What is the use of each network? Could you Please provide me a detailed answer or suggest me any document regarding this networks.

These are the nova-compute logs but I think it just catches the error from the neutron component. Any logs from neutron-server, ovs-agent, libvirt-agent?
Can you share the "openstack network show NETWORK_ID_HERE" of the network you are attaching the VM to?

There are essentially two types of networks, vlan and vxlan, that can be attached to a VM. Ideally, you want to look at the logs on the controllers and the compute node.
Openstack-ansible seems to send stuff here https://docs.openstack.org/openstack-ansible/mitaka/install-guide/ops-loggin... .

Hi Laurent, Thank you very much for your reply.we configured our network as per official document .Please take a look at below details. --->Controller node configured with below interfaces bond1,bond0,br-mgmt,br-vxlan,br-storage,br-vlan
---> Compute node bond1,bond0,br-mgmt,br-vxlan,br-storage
I don't have much more experience in openstack,I think here we used vlan network.

You will need to look at the neutron-server logs + the ovs/libviirt agent logs on the compute. The error returned from the VM creation is not useful most of the time.
Was this a vxlan or vlan network?
