[ovs-discuss] Error adding port to ovs-dpdk build

Hi Kevin,
Yes, Iam using dpdk 1.7.1.

Vswitchd:
./vswitchd/ovs-vswitchd --dpdk -c 0x1 -n 4 --socket-mem 20,0 -- unix:$DB_SOCK --pidfile --detach

Command used to add bridge:
./ovs-vsctl add-br br0 -- set bridge br0 datapath_type=netdev


Thanks,
Sharmila

Hi Sharmila,

Can you show the command line you run ovs-vswitchd with and the EAL screen prints regarding "Setting up memory...". Also the command you used to add the bridge. I'm assuming you are using DPDK 1.7.1?

Thanks,
Kevin.

Hi,
I have installed OVS with DPDK from github. I tried adding the port. Iam getting cannot allocate memory error for the port.


OVS version:

Kernel Version:

Hugepages setting:

The /var/log/messages had the following log:

What is that Iam missing?

Thanks,
Sharmila
