late to the party... but I'll dabble.

OVS provides much more robust monitoring and operational facilities
(e.g sFlow monitoring, better switch table visibility etc).
It also provides a linux-bridge compatibility layer (ovs-brcompatd
), which should work out-of-box with the linux-bridge. As such,
switching to using OVS rather than the linux bridge could be done
without any code changes to nova, just deployment changes (e.g. ensure
that ovs-brcompatd is running to intercept brctl ioctl's - ).
For the more adventurous, there could be any number of interesting
scenarios enabled by having access to ovs capabilities (e.g.

I'm similarly curious if any *operators* have experimented with OVS
and sFlow or other of its capabilities.
