I have installed openstack (Ocata) on centos 7. The architecture is as shown in the link above. All the VMs have access to the internet and everything within the VMs is working fine via the 'em1' port. I want to access the other two intel ethernet (i350) physical ports from VM1. How can I access and configure those two ports? Based on my research I tried to use SR-IOV or PCI passthrough, but couldn't get it to work. Please let me know if you need any other details. All suggestions are welcome. Thank you in advance.
