<p class="MsoNormal" style="background:white"><span style="font-size:10.0pt;font-family:"Helvetica","sans-serif";color:black">Hi there!<br>
<br>
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.<br>
<br>
I created network, subnet and ports successfully by following this doc:<br>
<a href="http://www.mellanox.com/related-docs/applications/Mellanox-OpenStack-Solution-for-Red-Hat.pdf">http://www.mellanox.com/related-docs/applications/Mellanox-OpenStack-Solution-for-Red-Hat.pdf</a><br>
<br>
I created an instance using following command:<br>
nova boot --flavor 1 --image 7f8460fd-6928-49ae-bef8-055a1de3e39a cirrOS --nic port-id=98f537b2-27dc-4583-ad1a-85edbd74987a<br>
<br>
The instance was in error state and eswitchd.log shows this:<br>
2014-01-26 09:41:36,549 DEBUG PF eth4, eths=['eth6', 'eth7', 'eth8', 'eth9'], vfs=[]<br>

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