Guys, Christian,

 After upgrading DPDK to "2.2.0-0ubuntu8", OpenvSwitch with DPDK is not
starting up anymore within a KVM Guest.

 Here is what I have in my Xenial KVM Guest:

---
root at template-1:~# dpdk_nic_bind --status

Network devices using DPDK-compatible driver
============================================
0000:00:05.0 'Virtio network device' drv=uio_pci_generic unused=
0000:00:06.0 'Virtio network device' drv=uio_pci_generic unused=

Network devices using kernel driver
===================================
0000:00:03.0 'Virtio network device' if= drv=virtio-pci
unused=uio_pci_generic
0000:00:04.0 'Virtio network device' if= drv=virtio-pci
unused=uio_pci_generic
---

apt install openvswitch-switch-dpdk

update-alternatives --set ovs-vswitchd
/usr/lib/openvswitch-switch-dpdk/ovs-vswitchd-dpdk

file "/etc/default/openvswitch-switch" contains:

-
DPDK_OPTS='--dpdk -c 0x1 -n 4 -m 1024'
-

 However, after running:

service openvswitch-switch restart

 There is no "ovs-vswit... --dpdk -c 0x1 -n 4 -m 1024" process!

 It was behaving differently before... I'll try rebuild it, or try to use
l2fwd DPDK App to test this VM...

 Any clue?

Cheers!
Thiago
