[ovs-discuss] Openvswitch with DPDK issue

[Sundar Ramakrishnan]

Thanks to Daniele, I have openvswitch compiled with dpdk. The way I installed is posted sundar-ramki/ovs-dpdk.

I have the following questions - 
1. How do I figure out if my VM is really using Openvswitch with DPDK?
2. Are there any counters for packets entering and leaving the switch and/or dpdk?
3. Also, I am unable to use the ofctl commands. Following is what I get - 
[root at test1 ~]# ovs-ofctl show br23ovs-ofctl: br23 is not a bridge or a socket[root at test1 ~]# ovs-vsctl showd8cfc890-a4fc-4398-869c-59c5412a3e79    Bridge "br23"        Port "eth3"            Interface "eth3"        Port "br23"            Interface "br23"                type: internal        Port "eth2"            Interface "eth2"
Any input will be appreciated.
Thank youSRK

 Hi,

OVS 2.3.2 supports DPDK 1.6, as stated in INSTALL.DPDK.
Many APIs have changed in DPDK in a backward incompatible
way.

Also, DPDK support in OVS 2.3.2 is experimental.  It would be
better to use the code from branch-2.4 (with DPDK 2.0)
