Hey, I'm not actually sure what the protocol is for adding/removing cores to a library project without a PTL, so I'm just going to put this out there: I'd like to propose the following changes to the os-vif core team. - Add 'nova-core' ...

Hi all, I promised John to dump my thoughts on traits to the ML, so here we go :) I see two roles of traits (or kinds of traits) for bare metal: 1. traits that say what the node can do already (e.g. "the node is doing UEFI boot") 2. traits ...

Please consider the support of MDEV for the /pci framework which provides support for vGPUs [0]. Accordingly to the discussion [1] With this first implementation which could be used as a skeleton for implementing PCI Devices in Resource ...

Hi, There's a few issues with devstack and the new zuulv3 environment LIBS_FROM_GIT is broken due to the new repos not having a remote setup, meaning "pip freeze" doesn't give us useful output. [1] just disables the test as a quick fix for ...

There is a desire to expose the vGPUs resources on top of Resource Provider which is probably the path we should be going in the long term. I was not there for the last PTG and you probably already made a decision about moving in that ...

Hi, We have a SRIOV capable NIC that supports OVS offload and Switchdev. We are trying to test the VifHostDevice model on a Pike cluster. We are running into issues. Here are the config options that we have used: 1. In Neutron conf file: ...

Hi everyone, I'm interested in set up a white boarding session at the ptg to discuss How to model network backend in placement and use that info as part of scheduling This work would also intersect on the nova neutron port binding ...

Hey, NUMA locality matters as much for NICs used e.g for Open vSwitch as for SR-IOV devices. At the moment, nova support NUMA affinity for PCI passthrough devices and SR-IOV devices, but it makes no attempt to do the same for other NICs. In ...

Will it be possible to include network bandwidth as a resource in Nova scheduling, for VM placement decision? Context: in telecommunication applications, the network traffic is an important dimension of resource usage. For example, it is ...

(I put [api] in the subject tags because this might be of interest to a wider audience that cares about APIs.) Long ago and far away I made this bug: https://bugs.launchpad.net/nova/+bug/1632852 "placement api responses should not be ...

Hi all, as per grafana [1] the functional job is broken. Looking at logstash [2] it started happening consistently since 2017-08-03 16:27. I didn't find any particular patch in Neutron that could cause it. The culprit is that ovsdb starts ...

Hi, I am experimenting with the os-vif library and stumbled upon this new VIF type called VIFHostDevice. I have few general queries. TIA. 1. How do I create ports with VIF_type as VIFHostDevice? Looking for the CLI command options. 2. Say, ...

Hi Nova team, I'm writing this e-mail because I'd like to have a discussion about DPDK support at OpenStack Summit in Boston. We have developed a dpdk-based patch panel named SPP[1], and we'd like to start working on Openstack (ML2 driver) ...

Hi We are approaching the non-client library freeze on Thursday. Below are a list of pending patches that I think will be good to review for inclusion in pike. Should have: Improve OVS Representor Lookup ...

Hi, In https://github.com/openstack/nova/blob/master/nova/virt/hardware.py#L396 we calculated every possible CPU topologies and sorted by: # We want to # - Minimize threads (ie larger sockets * cores is best) # - Prefer sockets over cores ...

We had a very lively discussion this morning during the Scheduler subteam meeting, which was continued in a Google hangout. The subject was how to handle claiming resources when the Resource Provider is not "simple". By "simple", I mean a ...
