[qa][all] pip 20.3 breaks jobs

senlin SR-IOV instance support
by Satish Patel 30 Nov '20

30 Nov '20

Folks, Does senlin support instance type SRIOV, I am successfully able to deploy using standard vm using virtio but for sriov instance we need to create a neutron port and then attach that port to VM. How does that process work with senlin? Currently I have the following profile: (if i want sriov instance then what i need to do?) type: os.nova.server version: 1.0 properties: name: cirros_server flavor: m1.small image: "cirros" key_name: ssh-key networks: - network: net1 metadata: test_key: test_value user_data: | #!/bin/sh echo 'hello, world' > /tmp/test_file ~S

I'm sure there's a good reason but - as is often the case - I'm left wondering why this isn't broken for everyone! Any clues or suggestions gratefully received. Neil

OVS-DPDK poor performance with Intel 82599
by Satish Patel 30 Nov '20

30 Nov '20

Folks, I am playing with DPDK on my openstack with NIC model 82599 and seeing poor performance, i may be wrong with my numbers so want to see what the community thinks about these results. Compute node hardware: CPU: Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz Memory: 64G NIC: Intel 82599 (dual 10G port) [root@compute-lxb-3 ~]# ovs-vswitchd --version ovs-vswitchd (Open vSwitch) 2.13.2 DPDK 19.11.3 VM dpdk (DUT): 8vCPU / 8GB memory I have configured my computer node for all best practice available on the internet to get more performance out. 1. Used isolcpus to islocate CPUs 2. 4 dedicated core for PMD 3. echo isolated_cores=1,9,25,33 >> /etc/tuned/cpu-partitioning-variables.conf 4. Huge pages 5. CPU pinning for VM 6. increase ( ovs-vsctl set interface dpdk-1 options:n_rxq=4 ) 7. VM virtio_ring = 1024 After doing all above I am getting the following result using the Trex packet generator using 64B UDP stream (Total-PPS : 391.93 Kpps) Do you think it's an acceptable result or should it be higher on these NIC models? On the internet folks say it should be a million packets per second so not sure what and how those people reached there or i am missing something in my load test profile. Notes: I am using 8vCPU core on VM do you think adding more cores will help? OR should i add more PMD?

[ironic] [tripleo] RFC: lzma vs gzip for compressing IPA initramfs
by Dmitry Tantsur 30 Nov '20

30 Nov '20

Hi folks, I've been playing with ways to reduce the size of our IPA images. While package removals can only save us tens of megabytes, switching from gzip to lzma reduces the size by around a third (from 373M to 217M in my testing). What's the caveat? The unpacking time increases VERY substantially. On my nested virt lab the 217M image took around 5 minutes to unpack. I'm not sure how much it will impact real bare metal, please feel free to test https://review.opendev.org/c/openstack/ironic-python-agent-builder/+/764371 and tell me. So, what do you think? Switching to lzma by default will likely affect CI run time (assuming we still have DIB jobs somewhere...) and development environments, but it will also provide a visible reduction in the image size (which benefit all environments). Large TripleO images may particularly benefit from this (but also particularly affected by the unpacking time). Feedback is very welcome.

[openstack][neutron]How to establish existing Openstack in a single server to other multiple physical NIC port
by dangerzone ar 30 Nov '20

30 Nov '20

Hi, I have deployed packstack (All-In-One) openstack over single server and that openstack traffic is IN/Out via eth1 of the server and that's the network port configured during the packstack deployment. The server has 4 nic ports and only one (nic1) is used during openstack deployment. The openstack running good and my vm/vnf traffic can in/out via eth1. I would like to know how I can utilize other nic port (2,3,4) in my server so that openstack can leverage that port for my other VM/VNF that instantiate in my openstack. For example from the image attached, I want VM/VNF1 connect to nic2 and VM/VNF2 connect to nic3. Please advise how it can be done. I really hope someone could advise and help me further. Thank you. **This is standard openstack (deployed via packstack all-in-one) over single centos7 server that have 4 nic ports**
