[masakari] Proposal to cancel weekly meetings
by Radosław Piliszek 06 Oct '21

06 Oct '21

Dears, Due to low attendance and the current schedule being uncomfortable for me, I propose to cancel the weekly meetings and suggest we coordinate via this mailing list and do ad-hoc chats on IRC as I'm simply lurking there most of the time and answering the messages. Kind regards, -yoctozepto

[ironic][molteniron][qa] Anyone still using MoltenIron?
by Julia Kreger 05 Oct '21

05 Oct '21

Out of curiosity, is anyone still using MotltenIron? A little historical context: It was originally tooling that came out of IBM to reserve physical nodes in a CI cluster in order to perform testing. It was never intended to be released as it was tooling *purely* for CI job usage. The reason I'm asking is that the ironic team is considering going ahead and retiring the repository. Thanks! -Julia

Help with eventlet 0.26.1 and dnspython >= 2
by Thomas Goirand 04 Oct '21

04 Oct '21

Hi, As you may know, eventlet is incompatible with dnspython >= 2.0.0.0rc1. See [1] for the details. However, Debian unstable has 2.0.0. Would there be some good soul willing to help me fix this situation? I would need a patch to fix this, but I'm really not sure how to start. Cheers, Thomas Goirand (zigo)

I can update the version as soon as the new version releases by using Fedora's release monitoring system. Thanks in advance, Hirotaka Wakabayashi

Hello Requirements Team, The Cinder team recently became aware of a regression in os-brick that prevents Nova from attaching NVMe volumes [0].

Thank you for your attention to this matter.

how dpdk improve guest performance
by Satish Patel 30 Sep '21

30 Sep '21

Folks, If I am running dpdk in my compute nodes then sure it will reduce kernel overhead but how does it help to improve guest network performance? Inside guest vm it's going to use kernel to copy packet to userspace. in my example we run high performance haproxy which handles 300k to 500k connections but I have noticed performance is poor and lots of packet drops. If I run the same workload on SRIOV vms it works fine and I notice less kernel context switching inside the guest VM. I think when you run DPDK in compute then it only help compute but not your guest network performance. How do I improve guest performance also with dpdk based compute?
