We certainly care about this but converting the XenServer CI to Neutron+OVS has 
been hitting a number of issues (notably a few concurrency ones – although 
there are a few missing features) that we’ve been trying to sort through.

I am certainly hoping that we’ll have everything stable enough to set up a CI 
specifically for this combination before the Kilo release and would be very 
keen not to deprecate XenAPI support in Kilo.
Certainly even if we don’t make the Kilo release for the CI we will still be 
pushing for it in L.

It might make sense to send this to the users list as well. There may be a 
large deployment out there with resources willing to at least test changes even 
if they don't have any upstream development resources.

There have been a couple of patches [1] [2] proposed to neutron recently that 
could impact our support for Xen+OVS, but I don’t see an easy way for us to 
validate such changes.  I’m not aware of a 3rd party CI job that runs against 
Xen, and I don’t know of any active contributors able to manually validate 
changes.  Unless this changes, I think we should consider deprecating support 
for Xen in kilo.  We can’t afford to block changes for fear of breaking 
something that nobody seems to care about.

I’m hoping this post serves as a wake-up call to anyone that wants to see 
neutron maintain its support for Xen, and that they will be willing to devote 
resources to ensure that support for it continues.  I’ve also added this issue 
to next week’s irc meeting [3].
