[Loftus, Ciara]

Does it work when you use the uio_pci_generic driver?

Thanks,
Ciara

  sorry, it is a obvious mistake in writing. and after I corrected it, this cmdline didn't work.


# ovs-vsctl add-port br0 dpdk-p0 -- set Interface dpdk-p0 type=dpdk options:dpdk-devargs=0000:83:00.0

ovs-vsctl: Error detected while setting up 'dpdk-p0': Error attaching device '0000:83:00.0' to DPDK.  See ovs-vswitchd log for details.

    I wonder whether there is other similar issue? and how to solve?


    I think you are adding the wrong device (::82). Try adding (::83).

Thanks,
Ciara





Hello,

I have installed OVS 2.7 running.  When I do:

# ovs-vsctl add-port br0 dpdk-p0 -- set Interface dpdk-p0

type=dpdk options:dpdk-devargs=0000:82:00.0

ovs-vsctl: Error detected while setting up 'dpdk-p0': Error attaching

device '0000:82:00.0' to DPDK.  See ovs-vswitchd log for details.



here is some informations：
