Date: Tue, 25 Dec 2018 13:40:32 +0000 [thread overview]
Message-ID: <bug-175-3@http.bugs.dpdk.org/> (raw)
https://bugs.dpdk.org/show_bug.cgi?id=175
Bug ID: 175
Summary: DPDK on Azure using `intel-go/nff-go` fails using
`hv_netvsc` driver
Product: DPDK
Version: 18.11
Hardware: Other
OS: Linux
Status: CONFIRMED
Severity: normal
Priority: Normal
Component: vhost/virtio
Assignee: dev@dpdk.org
Reporter: guesslin1986@gmail.com
Target Milestone: ---
Overview: running DPDK on Azure using `intel-go/nff-go` library fails with
`Requested receive port exceeds number of ports which can be used by DPDK (bind
to DPDK). (3)`
Steps to Reproduce:
1) build binary from
https://gist.github.com/guesslin/76be1139e5e3b8d71e964e194c5d9322
2) run `app -d uio_hv_generic -n <NICName>`
Actual Results:
$ sudo ./app -d uio_hv_generic -n eth2
2018/12/25 06:58:49 Binding PMD driver eth2 to NIC uio_hv_generic
