[Openstack-operators] [scientific] Resource reservation requirements (Blazar) - Forum session

Hi all, The below was suggested for a Forum session but we don't yet have a submission or name to chair/moderate. I, for one, would certainly be interested in providing input. Do we have any owners out there? Resource reservation requirements: == The Blazar project [https://wiki.openstack.org/wik

Re: [Openstack-operators] [scientific] Resource reservation requirements (Blazar) - Forum session

Hi all, So I've proposed a Forum session to discuss some of these issues and use-cases: http://forumtopics.openstack.org/cfp/details/124 - there would seem to be value in getting Nova, Blazar and OPIE folks together to talk about advanced scheduling use-cases. In particular it looks like there is

Re: [Openstack-operators] [scientific] Resource reservation requirements (Blazar) - Forum session

Some combination of spot/OPIE and Blazar would seem doable as long as the resource provider reserves capacity appropriately (i.e. spot resources>>blazar committed along with no non-spot requests for the same aggregate). Is this feasible? Tim On 04.04.17, 19:21, "Jay Pipes" wrote: On 04/0

Re: [Openstack-operators] [scientific] Resource reservation requirements (Blazar) - Forum session

Hi all, I'm late to the discussion. Some of members in Blazar's team have an interest from NFV side for the resource reservation. So we have one usecase that telecom operators want to reserve instance slots at a specific time window because of expected workload increasing. I'm thinking the

Re: [Openstack-operators] [scientific] Resource reservation requirements (Blazar) - Forum session

Hi Tim, It does seem feasible, but imagine the aggregate juggling... it's something of an indictment that from where we are today this seems like a step forward. I'm not a fan of pushing that load onto operators when it seems like what we actually need is fully-fledged workload scheduling in Nova.

Hi scientific team, As Jay mentioned the previous mail, I drafted the instance reservation[1] of Blazar and some have already added their comments. 1. https://etherpad.openstack.org/p/new-instance-reservation Please adds your comments, concerns and/or what you want. It could make more clear
