Hi Nishant,
Mellanox plugin supports two types of VF provisioning , as pci passthrough (hostdev) and as macvtap (mlnx_direct) vNIC.
According to the log, you want to use the first flavor (hostdev).

Please follow the following instructions in: http://Community.mellanox.com/community/develop/<http://community.mellanox.com/community/develop/> - After the installation perform the following changes for  setting the 'probe_vf'  option in mlx4_core. In case you want all VFs to be used in pci passthrough mode, set the probe_vf = 0.

In case you need further assistance, please contact us at Openstack at mellanox.com<mailto:Openstack at mellanox.com>

Best Regards,
Irena

Subject: [Openstack] Need help on openstack mellanox quantum plugin setup

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 09:41:36,549 DEBUG PF eth4, eths=['eth6', 'eth7', 'eth8', 'eth9'], vfs=[]

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
