Open Stack

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.

Regards,
Pranav
