<pre>- As an infrastructure administrator, Anna wants to be able to unallocate a node from a deployment.
</pre>
<pre>Why? Whats her motivation. One plausible one for me is 'a machine
needs to be serviced so Anna wants to remove it from the deployment to
avoid causing user visible downtime.' So lets say that: Anna needs to
be able to take machines out of service so they can be maintained or
disposed of.</pre>

Node being serviced is a different user story for me.<br>

I believe we are still 'fighting' here with two approaches and
I believe we need both. We can't only provide a way 'give us
resources we will do a magic'. Yes this is preferred way -
especially for large deployments, but we also need a fallback
so that user can say - no, this node doesn't belong to the
class, I don't want it there - unassign. Or I need to have
this node there - assign.</blockquote>
<div>Just for clarification - the wireframes don't cover
individual nodes being manually assigned, do they? I thought
the concession to manual control was entirely through resource
classes and node profiles, which are still parameters to be
passed through to the nova-scheduler filter. To me, that's
very different from manual assignment.<br>

It's all doable and wireframes are prepared for the manual
assignment as well, Mainn. I just was not designing details for now,
since we are going to focus on auto-distribution first. But I will
cover this use case in later iterations of wireframes.<br>
