Hi....as far I understand ovs does support dpdk compute to be deployed. I'm referring to the guideline ' *https://docs.openstack.org/networking-ovn/queens/admin/dpdk.html <https://docs.openstack.org/networking-ovn/queens/admin/dpdk.html>* ' ... It's too brief.. May I know how to config dpdk compute in OVN networking openstack? Hope someone could help what is the config to be done.... Currently compute is run without dpdk over openstack train ovn based. Please need some info on how I can proceed. Thank you

Thanks Andy. Regards. Forwarded Conversation Subject: [MURANO] DevStack Murano "yaql_function" Error ------------------------ Gönderen: Andy Botting <andy(a)andybotting.com> Date: 30 Nis 2020 Per, 14:13 To: İzzettin Erdem <root.mch(a)gmail.com> Cc: Rong Zhu <aaronzhu1121(a)gmail.com>, < openstack-discuss(a)lists.openstack.org> Hi İzzettin, Thanks for your interest. Complete log link is at below. It is happening > when i try to deploy or update an environment. > > http://paste.openstack.org/show/792444/ > I've encountered the error AttributeError: 'method' object has no attribute '__yaql_function__' in our environment recently. I believe it started after we upgraded to the Stein release. I haven't tracked it down yet, but calls to the YAQL function: std:Project.getEnvironmentOwner() in a Murano app seem to generate it. It's good to know that at least someone else has reproduced this. cheers, Andy ---------- Gönderen: İzzettin Erdem <root.mch(a)gmail.com> Date: 2 May 2020 Cmt, 16:08 To: Andy Botting <andy(a)andybotting.com> Hi Andy, I solved this problem, it is happening when you try to create or update an environment on existing network. If you change the network with "create new" parameter, it stuck on "creating -or updating- environment" state and after that throws connection error. So i searched Murano network errors and i found this: https://docs.oracle.com/cd/E73172_01/E73173/html/issue-21976631.html. I applied these steps and i created successfully an environment just only with "create new" network parameter. After all these, i realized my devstack environment has no internet connection and because of this murano-agent could not install. So i tried to install Murano on my OSA stable/train test environment and i came with success until last step. Murano-agent installed but this time agent could not connect to rabbitmq instance. I discussed this with OSA IRC channel and i think i have to struggle with this for a long time. Apologize for this long mail but i wanted to inform you. Thanks. Regards. ---------- Gönderen: Andy Botting <andy(a)andybotting.com> Date: 3 May 2020 Paz, 14:24 To: İzzettin Erdem <root.mch(a)gmail.com> Hi İzzettin, Glad you got it sorted. I think you've probably just worked around the issue. Using your new method, you're probably just avoiding the std:Project.getEnvironmentOwner YAQL call now. I've also worked around it in our environment, but I'd like to solve it properly. When I get some time to look into it properly, I'll let you know. cheers, Andy

Weird iptables problem
by Florian Rommel 01 Nov '20

Hi, so we deployed a test cluster with 8 total nodes. Openstack ussuri, Ubuntu 20.04 , opevswitch, octavia. Everything works more or less as it should , however when deploying a loadbalancer (which works perfectly), instances on the same node as the amphora deployment loose all access via public up after open switch logs a message : modified security group “long uuid”, which is a sec group belonging to octavia. What effect does that have with the rest? Questions: Should ufw be on and started? How can we troubleshoot this more in depth? Why does the lb work perfectly whole instance with floating up loos all access from the internet but the lb works fine passing thru the web services. One more thing. Does anyone have a recommended sysctl.conf Settings list for Ubuntu/ openstack ussuri? Thanks already and have a nice weekend, //f
