[nova][scheduler] nova scheduler to balance vms more randomly
by Satish Patel 27 May '24

27 May '24

Folks, I have noticed when I spin up a bunch of vms then they all go to the same hypervisor until it runs out of resources. I can understand that it's trying to fill the hypervisor before it picks the next one. But it's kind of dangerous behavior. For example one customer created 3 vms to build a mysql galera cluster and all those 3 nodes endup on the same hypervisor (This is dangerous). I would like openstack to pick the hypervisor more randomly if resources are available in the pool instead of trying to fill the hypervisor. How do I change that behavior? ( There is a feature called affinity but again I would like nova to place vm more randomly instead shaving all to a single node). I am not an expert in scheduler logic so please educate me if I am missing something here.

Difficulty Create/Upload Images
by Cakra Wirabuana 24 May '24

24 May '24

Hi everyone, I have a difficulty when creating image. I have downloaded the file with both .img and .iso formats and I have tried various format options (QCOW2, RAW, ISO, etc) but it still fails and a notification appears as in the image I attached to this email. Does anyone know the cause of this and what is the solution? If it turns out that I have to create an image via CLI, how do I do it? I am using Ubuntu 22.04.4 LTS. Thank you, Cakra Wirabuana [image: image.png]

cpu steal
by Gk Gk 22 May '24

22 May '24

Hi, If we create pinned vms, is there a chance of cpu steal in this scenario ? If so what could be the reason since we have dedicated cpu assigned to the guest ? What would happen if it is a physical cpu, directly assigned to the vm ? Does it experience cpu steal in this case as well ? Thanks GK

[kolla-ansible] How to pin pip3 module in kolla-ansible
by Satish Patel 22 May '24

22 May '24

Folks, I have deployed kolla-ansible using public images so far everything is good until I hit this bug [1] requests pip module had a minor bug. Now my question is if I want to pin requests==2.31.0 version in kolla-ansible then what file should I be adding to the pin version? This is not an image building related module because it deployed on a metal host so nothing to do with building kolla images. It's a pure docker issue. 1. https://github.com/docker/docker-py/pull/3257

[tc][all][sahara] Retiring the Sahara project
by Ghanshyam Mann 21 May '24

21 May '24

Hello everyone, As you might know, the Sahara project is not active and was marked 'inactive' since 2024.1 cycle[1]. In this cycle also, this project is leaderless[2] and no maintainer stepped up to maintain it. As discussed in the Leaderless project etherpad[2], the next step is to retire the project. I'm sending this email to propose the Sahara retirement and based on the response, I will proceed next.

[openstack][nova]about instance-state when resizing failed
by Nguyễn Hữu Khôi 21 May '24

21 May '24

Hello. I would like to know why we set instance-state to ERROR when resizing/migrating failed? I have a problem with resizing/migrating instances. I must reset state then shelve and unshelve instances to make it come back. Thank you for your time. Nguyen Huu Khoi
