DPDK Poor performance
by Satish Patel 29 Sep '21

29 Sep '21

Folk, I have deployed DPDK on one of my compute nodes to reply to my sriov deployment which doesn't support bonding. This is what I am doing to do a performance benchmark. Spun up VM with 8 vCPU and 8GB memory with single virtual nic. Then install nuttcp tool and start nuttcp -S (server mode) and then use Physical server outside my lab and use following command to blast some traffic nuttcp -T 30 -i -u -w4m -R 2G 10.69.7.130 I found 120kpps rate working fine but after that I noticed a packet drop on nuttcp. Here is the full details of my deployment and load-test result - https://paste.opendev.org/show/809675/ Small confusion related hugepage - I am seeing following in /dev/hugepages/ I believe rtemap_0 created by DPDK root@ovn-lab-comp-dpdk-1:~# ls -l /dev/hugepages/rtemap_0 -rw------- 1 root root 1073741824 Sep 29 02:28 /dev/hugepages/rtemap_0 Why is the qemu instance file empty? Does that mean it's not using a huge page for dpdk performance? root@ovn-lab-comp-dpdk-1:~# ls -l /dev/hugepages/libvirt/qemu/1-instance-00000045/ total 0 I have hw:mem_page_size='large' setting in flavor so it should use hugepage. am i missing something?

[Cinder] [Nova] [Interop] "compute-volume-list" API guideline
by Vida Haririan 29 Sep '21

29 Sep '21

Hi Cinder and Nova teams, The Interop team is reviewing all related open stories to determine next steps. We researched the current status of 1638112:“os-volumes should be flagged for removal in the compute API guidelines“ [1] and noticed that "compute-volume-list" was removed in 2017.01 guidelines [2][3]. However, two related tests still remain in tempest [4][5] and we are reaching out to determine if the API is still in use or has been moved/renamed. Please let us know if you have any questions. [1] https://storyboard.openstack.org/#!/story/1638112 [2] https://opendev.org/osf/interop/src/commit/dd7ae2660de5daa82ab4fe080e875d63… [3] https://opendev.org/osf/interop/src/branch/master/guidelines/next.json [4] https://opendev.org/openstack/tempest/src/commit/ae41052a51f5dbb748eb6bf4f2… [5] https://opendev.org/openstack/tempest/src/commit/ae41052a51f5dbb748eb6bf4f2… Thank you, -- *Vida Haririan* Senior Software Quality Engineer Red Hat EMEA <https://www.redhat.com/>

[announce][debian][xena] general availability of OpenStack Xena in Debian
by Thomas Goirand 29 Sep '21

29 Sep '21

Hi! It's my pleasure to announce the general availability of OpenStack Xena in Debian. Indeed, I've just finished uploading everything to Debian Experimental at the beginning of this week, and was able yesterday, to pop my first VM over on top of Xena. This marks the first readiness of the release, from the Debian point of view (even though there probably will be things to fix, like after addressing https://bugs.launchpad.net/oslo.policy/+bug/1945336 for example, and uploading the final release to replace the RCs when that becomes available). The Bullseye backports are available the usual way, for example using extrepo: apt-get install extrepo extrepo enable openstack_xena apt-get update ... or directly setting-up the http://bullseye-xena.debian.net repository the usual way. I'm currently in the process of uploading all of Xena to Debian Unstable (but please bare with me: there's 225+ packages in this update). Note that Xena can already be installed by OCI [1]. Please report any issue you may find, on OCI or on the Debian packages, through the Debian BTS as usual. Cheers, Thomas Goirand (zigo) [1] https://salsa.debian.org/openstack-team/debian/openstack-cluster-installer
