<div dir="ltr">Hi,<div><br></div><div>Thanks for the reply!</div><div><br></div>I read through the BPs and especially the first one ("Create volume in same host in which vm instance is running") seems to be implementing what I want. Where can I get information about the status of the implementation of the BPs? Will they be integrated in Icehouse? The Launchpad pages don't quite answer this...</div>

OTOH, I would still like to take advantage of nova-scheduler for automatic host selection for VMs. I don't want to use an availability zone per host, because then the host selection would have to be done by the API client. So I'm wondering what the best solution for this use-case might be.</div>
<div><br></div><div>While researching, I stumbled upon topology aware placement [0] which seems interesting, but I couldn't find any further information about the status of it. Also, there seems to be some effort going into building a central scheduler instead of having nova-scheduler and cinder-scheduler [1][2], but again, I couldn't figure out what the current status of this is.</div>
<div><br></div><div>So, my question is if this use-case will be better supported in the future (Icehouse maybe already?), and how a workaround could look like for now.</div><div><br></div><div>Thanks a lot,</div><div>Thomas</div>
