[ovs-discuss] enabling trunk for multiple on openvswitch

[nisha goyal]

Hi Ben,

I figured out that the problem is that the ovs is not able to write the
configurations for the VMs into its db. Please refer to the excerpts from
the ovs-vswitchd.log file:

Oct 07 15:18:54|00031|bridge|INFO|created port br0 on bridge br0

There are no datapath IDs created for vnet0, vnet1 and so on. Can you
please tell me, what could be the possible cause for it?
