[dpdk-users] OVS Switch with DPDK

[shyam yeduru]

yep!! I am testing 4 different scenarios i.e

1.SR-IOV with Vyatta vRouter
2.SR-IOV + DPDK with Vyatta vRouter
3.OVS with Vyatta vRouter
4.OVS + DPDK with Vyatta vRouter

>From the above 4 , we are good with 3 scenarios expect OVS+DPDK . We are getting errors while adding dpdk0 interface to OVS.

I have followed these websites to understand and configure it. but no l

Error mesg:

2016-06-22T06:18:28.972Z|00024|bridge|WARN|could not open network  device dpdk0 (No such device)

Thanks
