Hi Erik,

 

Thanks for your response. Getting below error message when I execute the command in compute node. Could this be the reason?

 

ubuntu@os-compute-01:~$ nova-manage cell_v2 discover_hosts --verbose

Maybe the compute isn’t yet mapped to the cell.

Please check the nova-compute log on os-compute-01 to see if any useful info.

Hi,

 

I’m trying to setup a multi-node OpenStack environment with OVS-DPDK. Unfortunately I’m running into issue that compute node not getting listed in hypervisor list as below screenshot. Due to this I’m unable to create instances on compute node.

 

Herewith I had attached the local.conf files of both controller and compute node. Can someone help me to resolve this issue.

 

 

Thanks & Regards,

Elan
