Hi, When I try to add a port with dpdk, I met an error: "Error attaching
device '0000:02:00.0' to DPDK". This is the instruction: ovs-vsctl add-port br0
dpdk-p0 -- set Interface dpdk-p0 type=dpdk
options:dpdk-devargs=0000:02:00.0 I have searched github and many mails, but I
still cannot find the solution(for a long time) :(:(. So can you tell me how
to solve it?
I have set CONFIG_RTE_BUILD_SHARED_LIB=y in $DPDK_DIR/config/common_base.

These is my main tutorial.

And I bind devices to VFIO:

============================================
0000:02:00.0 'Ethernet Controller 10-Gigabit X540-AT2 1528' drv=vfio-pci
unused=ixgbe
0000:02:00.1 'Ethernet Controller 10-Gigabit X540-AT2 1528' drv=vfio-pci
unused=ixgbe
And I ensure them initialized
root@sdn:/usr/src/ovs# ovs-vsctl get Open_vSwitch . dpdk_initialized
true
root@sdn:/usr/src/ovs# ovs-vswitchd --version
ovs-vswitchd (Open vSwitch) 2.10.90
DPDK 17.11.3
root@sdn:/usr/src/ovs# ovs-vsctl get Open_vSwitch . dpdk_version
"DPDK 17.11.3"
Then I add a bridge
ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev
Add a port:
root@sdn:/usr/src/ovs# ovs-vsctl add-port br0 dpdk-p0 -- set Interface dpdk-p0
type=dpdk options:dpdk-devargs=0000:02:00.0
ovs-vsctl: Error detected while setting up 'dpdk-p0': Error attaching device

ovs-vsctl: The default log directory is "/usr/local/var/log/openvswitch".
