To what end?
OVS provides much more robust monitoring and operational facilities (e.g sFlow monitoring, better switch table visibility etc).
You won't find any disagreement from me about OVS having more advanced capabilities :)
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 - ).
Using ovs-brcompatd would be possible, though some distros do not package and run it by default and in general it is not the "preferred" way to run things according to email on the OVS mailing list.
Indeed. While it's doable, it's not something that will hit upstream Linux, and therefore will not be supported by some distros.
But, in general...while adding OVS support to nova networking (in the simplest layer 2 switch mode), may not be much work. It's adding a (not particularly useful) feature to a code base that we hope to deprecate. And making it more useful (adding things like tunnelling) support are really the point of Quantum.
