[openstack-dev] [nova] [Pycharm]
Hello guys, are some of you using PyCharm to debugging and testing nova? I've cloned the Nova Project in my PC, and I want to run some unit tests with the debugger. I searched in these days, but I found nothing. Do you have some suggestions?

Hi Chris, > I'm pretty sure a regular user can create a server group and specify the > anti-affinity filter. yes, but we want that the user specifies just the Robustness; the way in which we assign the instances to the compute nodes should be a black box for the regular user(and also for the admin). > Why do you need to track which compute nodes the instances are on? Because putting the instances in the correct compute nodes is just the first step of the algorithm that we are implementing, for the next steps we need to know where is each instance. Thank you for the question.

Re: [openstack-dev] [nova-scheduler] Get scheduler hint
Thank you a lot for the help! I think that the problem can be solved using the anti-affinity filter, but we want a regular user can choose an instance and set the property(image, flavour, network, etc.) and a parameter Robustness >= 1(that is the number of copies of this particular instance). After that, we put every copy of this instance in a different compute, but we need to track where we put every copy of the instance (we need to know it for the algorithm that we would implement); EXAMPLE. With 4 compute nodes User create an instance(Server_1) with Robustness = 3. Server_1_copy1 ==> compute2 Server_1_copy2 ==> compute1 Server_1_copy3 ==> compute4 User create another instance (Host_1) with Robustness = 2 Host_1_copy1 ==> compute2 Host_1_copy2 ==> compute3 and we want to track in a table where are the copies of a particular instance. For Server_1 copy1 ==> compute2 copy2 ==> compute1 copy3 ==> compute4 same thing for Host_1 copy1 ==> compute2 copy2 ==> compute3 I hope that now is more clear. In your opinion what is the best way to do it?

Re: [openstack-dev] [nova-scheduler] Get scheduler hint
Thank you a lot! :-). Actually, we are also working in parallel to implement the algorithm with tacker, but for this project we will only use the basic modules in OpenStack and Heat. If the scheduler hints are no longer supported, what is the correct way to give the scheduler personalized input with the instance details?

Re: [openstack-dev] [nova-scheduler] Get scheduler hint
Thank you for your answer :-) I'm pretty new in OpenStack and open source in general(I started two months ago, and I don't have any experience in developing big project). What we are trying to do is to implement our algorithm for Robust NFV chain; to do it we need to create multiple copies of the same instance and put them in different compute nodes. When we create an instance, we give as input the robustness(integer value >=1) that is the number of copy of an instance. For example Robustness = 3, it will create 3 instances and put them in 3 different compute nodes.

[openstack-dev] [nova-scheduler] Get scheduler hint
Hello all, I’m modifying nova-scheduler, implementing my own scheduler; there is a way to get all the list of the scheduler hints(for example when I lunch a new Instance, add a custom Hint MY_HINT, with value 100)? I tried with def select_destination(self, context, spec_obj): ….. spec_obj.get_scheduler_hint(‘MY_HINT’) # but it return None ….. thank you Giuseppe Di Lena __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
