Hi Yuling, I am getting similar issues with Havana, but in my case I saw that OVS 1.10 shows build error while compiling its packages. Can you do
# dpkg-reconfigure openvswitch-datapath-dmks (assuming you are using ubuntu/debian) or something similar and check the output, esp. when its recompiling the kernel.
