Hey Christian,

After latest release on Xenial, it looks very good! Both UIO and VFIO works
without effort.

I can easily switch between UIO and VFIO, that DPDK shows the NICs being
used as "DPDK-Compatible drivers".

Only OpenvSwitch+DPDK doesn't see any "dpdk0 | dpdk1" devices but, I know
you guys are working into this...

Sounds great!

That sounds like a good plan, I totally understand that...   =)

You can count on me! I'm a big fan of Ubuntu...

I met Mark in Vancouver on OpenStack summit, he is a great guy and it is
easier now to see why Ubuntu is so cool! A lot of amazing people working
here!     ^_^

So I wanted to ask if you could be patient for a few days, once my Env is

Of course! I'll be the beta tester.    ;-)

Just for the record, we moved this thread to Ubuntu Server, here is the
previous thread on Ubuntu Devel, so, people on Ubuntu Server will
understand what we're talking about:
