This is a repost of https://lists.01.org/pipermail/dpdk-ovs/2014-September/001788.html as the issue might be related to dpdk.org vhost code.

I am using dpdk-ovs 1.1.0 (latest release) as follow :

linux-guest (no DPKD) <---  virtIO ---> OVDK 1.1.0 (with latest DPDK [*]) < --- Niantic --- > linux-native

UDP/ICMP connectivity is fine, but TCP checksum of packet sent by the guest are incorrect, as showed with tcpdump on linux-native.

Is it supposed to work? If yes, what is the proper qemu version to use and its parameters?

I am using qemu version provided by dpdk-ovs (same issue with PDDK 1.7.0 and latest one) and I followed this documentation: https://github.com/01org/dpdk-ovs/blob/development/docs/04_Sample_Configurations/02_Userspace-vHost.md
