Please forgive the apparent aggressive attitude of this statement.
Allow me to rectify:
"Everybody who deploys Xen, KVM, or LXC can choose to use Open vSwitch,
which comes as the default selection in some case".
It was not my intention to make a statement regarding networking in
Hypervisors, and this kind of discussion also is rather off-topic for this
thread.

Correct. Unfortunately I did not have more information on the question. So
I just limited myself to give a few pointers to spur a discussion on what
the originator of thread claimed by "openvswitch without quantum".
