Nova-conductor is having trouble with AMQP authentication
by Airamek 07 Jul '22

07 Jul '22

Hello everyone! I've installed OpenStack Ussuri on my home servers (one controller and one compute node, both running OpenSuse Leap 15.3) based on the instructions in the docs(https://docs.openstack.org/install-guide/openstack-services.html#minim… Everything works until I launch an instance in Horizon. The instance gets stuck on "Scheduling". Looking trough the logs I've came across nova-conductor.log(on the controller), which contained the following error log(full log in the attachments): 2022-07-08 00:48:08.846 25886 ERROR oslo_messaging.rpc.server [req-eb225ffd-9b12-4e80-987b-34f0317082c6 741cb0b6280cb6fbedf1d8c6df4fc854b3e177e331441e019b961839089154d6 9b41f3e228984401a7642f94cd47dc73 - 4596c7f3b97740b3adfa8f82b6240654 4596c7f3b97740b3adfa8f82b6240654] Exception during message handling: amqp.exceptions.AccessRefused: (0, 0): (403) ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN. For details see the broker logfile. I'm 100% sure my RabbitMQ username and password are set correctly in nova.conf. I've included my nova.conf too, with the passwords removed. I would be really thankful, if someone could point me in the right direction! P.S: Please excuse me for any grammatical or spelling mistakes, English is not my first language.

If you're interested in participating in an informal discussion between the OpenStack TC, OpenInfra board members, and other interested community collaborators, don't forget to mark your preferred dates and times by Friday, 2022-07-15, so that I can let the board members know what our collective availability looks like: https://framadate.org/atdFRM8YeUtauSgC If you don't know what this is about, see my earlier post for details (I intentionally avoided replying to it in order to increase visibility for the reminder): https://lists.openstack.org/pipermail/openstack-discuss/2022-June/029352.ht… -- Jeremy Stanley

[manila] Stepping down from manila core
by Rodrigo Barbieri 07 Jul '22

07 Jul '22

Hello fellow zorillas, It has been a long time since I started to hope every day I'd able to dedicate more time to manila core activities and so far that hasn't happened and I don't see it happening in the near foreseeable future. I had been following the meetings notes weekly until ~2 months ago but I recently ended up dropping those as well. Therefore I am stepping down from the manila core role. I would like to thank everyone that I worked closely with from 2014 to 2019 on this project. I hold this project and all of you dear to my heart and I am extremely glad and grateful to have worked with you and met you on summits/PTGs, as the life memories around Manila are among the best I have from that period. If someday circumstances change, the manila project and its community will be ones I will be very happy to go back to working closely with again. Kind regards, -- Rodrigo Barbieri MSc Computer Scientist

Openstack instance is unreachable
by GEORGIOS PAPATHANAIL 07 Jul '22

07 Jul '22

I am facing the following issue with my new Openstack installation. The installation is a little bit weird and to elaborate more, I have a controller and a compute node running as VMs in XenServer. The compute node has nested virtualization enabled and uses qemu in order to provision VMs. I have a provider flat network that has a public range of IPs and VMs use this network. I am able to create instances and access them via console, but I can't ping them or ssh even if they have public IPs. I am not very familiar with Xen Server, is there any configuration that is needed (bridges, promisc mode, etc)? -- *George Papathanail* *Associate Researcher* *Department of Applied Informatics* *University of Macedonia*

Poor I/O performance on OpenStack block device (OpenStack Centos8:Ussuri)
by Vinh Nguyen Duc 07 Jul '22

07 Jul '22

I have a problem with I/O performance on Openstack block device HDD. *Environment:**Openstack version: Ussuri* - OS: CentOS8 - Kernel: 4.18.0-240.15.1.el8_3.x86_64 - KVM: qemu-kvm-5.1.0-20.el8 *CEPH version: Octopus * *15.2.8-0.el8.x84_64* - OS: CentOS8 - Kernel: 4.18.0-240.15.1.el8_3.x86_64 In CEPH Cluster we have 2 class: - Bluestore - HDD (only for cinder volume) - SSD (images, cinder volume) *Hardware:* - Ceph-client: 2x10Gbps (bond) MTU 9000 - Ceph-replicate: 2x10Gbps (bond) MTU 9000 *VM:* - Swapoff - non LVM *Issue*When create VM on Openstack using cinder volume HDD, have really poor performance: 60-85 MB/s writes. And when tests with ioping have high latency. *Diagnostic* 1. I have checked the performance between Compute Host (Openstack) and CEPH, and created an RBD (HDD class) mounted on Compute Host. And the performance is 300-400 MB/s. => So i think the problem is in the hypervisor But when I check performance on VM using cinder Volume SSD, the result equals performance when test RBD (SSD) mounted on a Compute host. 2. I already have to configure disk_cachemodes="network=writeback"(and enable rbd cache client) or test with disk_cachemodes="none" but nothing different. 3. Push iperf3 from compute host to random ceph host still has 20Gb traffic. 4. Compute Host and CEPH host connected to the same switch (layer2). Where else can I look for issues? Please help me in this case. Thank you.

[large-scale][cinder] backend_native_threads_pool_size option with rbd backend
by Arnaud Morin 07 Jul '22

07 Jul '22

Hey all, Is there any recommendation on the number of threads to use when using RBD backend (option backend_native_threads_pool_size)? The doc is saying that 20 is the default but it should be increased, specially for the RBD driver, but up to which value? Is there anyone tuning this parameter in their openstack deployments? If yes, maybe we can add some recommendations on openstack large-scale doc about it? Cheers, Arnaud.
