Please refer to the mailing list post with subject: "Provisioning changes to host interface commands" which I have attached to this message.

But now I got the following error: system: error: unrecognized arguments: -p 47569880-3225-4a96-b897-b7bf1d114b8d Seems that there is an error in the structure or syntax of command, but -p flag and interface UUID are separated by other parameters. I also try to use -d flag and interface name instead of uuid but got the same error. Do you know if this SRIOV command have changed? Regards. Juan Carlos Alonso
