Hi team,

Please could you pour in your suggestions on the mail?

I raised a blueprint in Nova for this
https://blueprints.launchpad.net/nova/+spec/pci-passthorugh-for-ironic and
two RFEs at ironic side https://bugs.launchpad.net/ironic/+bug/1680780 and
https://bugs.launchpad.net/ironic/+bug/1681320 for the discussion topic.

Regards
Nisha
