[ovs-dev] ovsdb-tool: error while loading shared libraries: librte_eal.so.6.1

Thu May 10 00:15:21 UTC 2018

Hi Ben,
I have solved that problem(set up all in the same terminal, and http://dpdk.org/ml/archives/dev/2016-June/042113.html). Now I did 
$ovs-vswitchd --version

ovs-vswitchd (Open vSwitch) 2.9.0
DPDK 17.11.1

and I also did
 $ sudo ovs-vsctl list open-vswitch
_uuid               : 048bdd81-a839-4232-b34d-93d85c3c5453
bridges             : [488018e3-f7dd-4646-ba1f-88277804ccf6, 88ecba3d-dab9-4437-8800-77e35af4cbb7, a62f9392-b5fa-44f2-a841-3af6c932a359]

other_config        : {dpdk-init="true", dpdk-socket-mem="1024"}
ovs_version         : "2.9.0"
ssl                 : []
statistics          : {}
system_type         : Ubuntu
system_version      : "16.04-xenial"

I just want a simple ovs which could support meter, the recent problem is that when I start mininet, it gets stuck like below:
*** Creating network
*** Adding controller
*** Adding hosts:
h1 h2 h3 
*** Adding switches:
s1 s2 s3 
*** Adding links:
(h1, s1) (h2, s2) (h3, s3) (s2, s1) (s3, s2) 
*** Configuring hosts
h1 h2 h3 
*** Starting controller
c0 
*** Starting 3 switches
s1 s2 s3 ...

(no mininuet console)

And I checked the controller, the connection isn't successful.  It will be really complex, right? Should I switch to CPqD? Actually I have tried, but some of the components source was removed online. Could you give me a suggestion? Thank you!

Best regards,
Mingming

I have done something according to: https://docs.openvswitch.org/en/latest/intro/install/dpdk/ and https://docs.openvswitch.org/en/latest/intro/install/general/#general-building. But now I met a problem. (I think I have done with dpdk part because no errors showed)

But I still don't know exactly how to do so I can push a meter in ovs. Could you guide me more? What does it mean by "support meters in the userspace(DPDK) datapath only"? Thanks again!
