Hi there!
I have setup a compute node with openstack networking enabled by the mellanox neutron plugin on RH6.4. I have enabled SR-IOV and created 4 VFs. They all show up in ifconfig. I tried creating an instance using 'nova boot' command. However it is in error state.
I created network, subnet and ports successfully by following this doc:
http://www.mellanox.com/related-docs/applications/Mellanox-OpenStack-Solution-for-Red-Hat.pdf
I created an instance using following command:
nova boot --flavor 1 --image 7f8460fd-6928-49ae-bef8-055a1de3e39a cirrOS --nic port-id=98f537b2-27dc-4583-ad1a-85edbd74987a
The instance was in error state and eswitchd.log shows this:

2014-01-26 10:43:14,566 ERROR Create port operation failed
My queries are:
- Does my setup look ok?
- I guess since I am using SR-IOV, the adapter is presenting VFs as PFs to OS. Is this understanding correct?
- vfs list is empty (Log says vfs=[]). Is this OK?
Please comment/advise on what could be the issue.
Thanks,
Nishant
