Hi Daniele and Kevin
My env:
Host: Centos 7.0
qemu-2.3.0
dpdk-2.0.0
ovs master tree at commit 1190bedaea
boot commands:
qemu-system-x86_64 -enable-kvm -smp 4 -m 2048 -hda centos7-1.img \
-netdev tap,id=nic1,script=no,downscript=no,ifname=dpdkvhost1,vhost=on
-device
virtio-net-pci,netdev=nic1,mac=
We've experienced the same problem during our testing.

For instance, your
guest kernel can offload the TCP checksum to the virtio-net device,
which in turn uses the virtio-net header (that requires TAP driver
support) to postpone
sorry my fault
