Subject: [dpdk-dev] Using dpdk in KVM guest with sr-iov pass-thru
Date: Tue, 26 Nov 2013 20:55:53 +0900 [thread overview]
Message-ID: <00a001ceea9e$753b8390$5fb28ab0$%yoo@samsung.com> (raw)
Hello,
I'm having trouble using l2fwd example on top of KVM guest with sr-iov. Here
goes the detailed description:
Symptoms:
If I run l2fwd dpdk-app, this app does not receive any packets. Even worse,
pass-thru-ed device in KVM guest is not receiving any interrupts and more
over,
PF in host-side is not also receiving any packets. If I destroy the KVM
guest,
then PF starts receiving packets. (which is very wired right?)
Env:
- Sr-iov card: Intel Corporation I350 Gigabit Network Connection (rev
01)
- DPDK version: dpdk-1.5.1r1
- KVM installed with the packages in ubuntu server 64-bit
n Kernel version: 3.11.0-12-generic
- KVM guest (ubuntu server 64-bit; the same to host)
- CPU: i7-3770
- iommu enabled
Do you have any similar issues or any comments or pointers?
Thanks,
Jaeyong
