Error about dpdk ovs on AWS VM

Error about dpdk ovs on AWS VM

[topperxin]

Hi list
         I am doing something about compile DPDK OVS on AWS VM, while I met some problem,
         1. I can only set the hugepagesize to 2M, not to 1G, the reason is the cpu only has
             flag 'pse', which support only 2M huge page size, while not has pdpe1gb, which support 1G huge
             page size. So, if I only use 2M huge page size, can I running DPDK OVS ?
         2. When I run the command:
              /vswitchd/ovs-vswitchd --dpdk -c 0x1 -n 2 -- unix:$DB_SOCK --pidfile --detach

             I will get some Error log, such as below, and then when I want to bridge one of the containers NIC as dpdk type, I will get error as below:
=============================================
             ovs-vsctl: Error detected while setting up '1eb915d295254_l'.  See ovs-vswitchd log for details.
=============================================            

Who can give me some advice on how to debug these errors? thanks a lot.
