Hi Alex, This problem usually happens when there is not memory allocated to DPDK in the socket where the port is connected to. Please use the dpdk-socket-mem option to set the amount of memory for DPDK in the different NUMA sockets,
Example: ovs-vsctl --no-wait set Open_vSwitch . other_config:dpdk-socket-mem="1024,1024" Mauricio V, On Mon, Jun 20, 2016 at 9:25 AM, gowrishankar < gowrishanka...@linux.vnet.ibm.com> wrote: > On Monday 20 June 2016 08:21 AM, Wang, Alex wrote: > >> Hi There, >> >> I downloaded the master branch from github and tried to setup OVS with >> DPDK mode under Ubuntu16.04 kernel_4.4.0-21-generic.
