Hi all,
I've made an analyse a while a go how to use SolverScheduler with a policy
engine:
https://docs.google.com/document/d/1RfP7jRsw1mXMjd7in72ARjK0fTrsQv1bqolOriIQB2Y
Basically there should be a plugin that translates the policy into constraints
for
solver to solve. This was made using
+1 for ServerGroup quotas. It's been a while since this feature is
discussed and approved. As a public cloud provider we really want to get
ServerGroup into production. However, without quotas it is more harm than
gain. Since ServerGroup (and even its novaclient's command) is merged in
Icehouse,

I could do that but I think I need to be able to scale more without
the need to use this much resources. I will like to simulate a cloud
of 100 maybe
1000 compute nodes that do nothing (Fake driver) this should not take
this much memory. Anyone knows of a more efficient way to simulate
Agreed. I'm just thinking on the opportunity of providing a REST API

done easily by defining a policy to each Pclouds. Future development of
the policy system will even allow users to define their own rules in their
Pclouds!

Thank you for yor example. I have some remarks concerning the JSON format:

this case there are two different declaration formats for members, as with

Just a small idea: is it OK if we use a file, or a database as a central point
to store the policies

scheduler drivers

We worked on it in Havana, learned a lot from feedbacks during the review
cycle, and hopefully will finalize the details at the summit and will be
able to continue finish the implementation in Icehouse. Would be great
