Hi All,

My host and VM both are running Fedora 23.

In the host, DPDK (testpmd, l2fwd and l3fwd) works fine.

Then I set up OVS with DPDK and pass two (dpdkvhostuser) ports to the VM.

In the VM, l2fwd works fine, but testpmd fails to start. Pleas see the
attached screenshot of the VM with error messages.

Has anybody seen similar issue in the VM?

Thanks,

Charlie
