Thanks Hugo for the suggestion. I went through Openstack documentation and check the Bios enabled VT-d and intel_iommu=on in kernel parameters. The same error is still there when launched a VM. I checked nova-compute log but nothing print out during the error.
My 'nova-tsn-pt.yaml' is exactly as above, not sure what is going wrong. Let me know if you have any other suggestion.
