Hi all,

I'm using OVS2.8.0+DPDK17.05+Intel_82599_IXGBE for test, the vf driver is
ixgbevf-4.0.3.

I use sriov follow like this:
echo 1 > /sys/bus/pci/devices/0000:01:00.0/max_vfs

Then test l3fwd-vf demo, it is OK.

Then test OVS2.8.0, and assign pf for ovs like this:
ovs-vsctl add-port br_t dpdk-p0 \
   -- set Interface dpdk-p0 type=dpdk options:dpdk-devargs=0000:01:00.0

Then I want to link up vf in linux driver, but report error
# sudo ifconfig em1_0 up
SIOCSIFFLAGS: Network is down

And log shows this:
kernel: ixgbevf 0000:01:10.0: PF still in reset state.  Is the PF interface
up?

And of course dpdk-p0 could NOT work.

But I found if I close sriov, dpdk-p0 could work.


So is this means sriov could not work in
OVS2.8.0+DPDK17.05+Intel_82599_IXGBE? Who have ever run success? Thank you~
