Hello Koller.I want to ask if we can overwrite config for a group of nodes. For example,compute01 >> compute10 will have the same nova configurationcompute11 >> compute20 will have the same nova configuration.It will be very nice if we support this way.Thank you. RegardsNguyen Huu Khoi

Fwd: DPDK+OVS with OpenStack
by Mark Wittling 23 Apr '25

23 Apr '25
Looking for someone who knows OpenStack with OpenVSwitch, and in additionto that, DPDK with OpenStack and OVS.I am using OpenStack Queens, withOpenVSwitch. The architecture I am using is documented here:https://docs.openstack.org/neutron/queens/admin/deploy-ovs-provider.htmlTheOVS I am using on the Compute Node, is compiled with DPDK, and I haveenabled the datapath to netdev (DPDK) on br-prv (provider network bridge),and br-tun (tunneling bridge). But these two bridges, br-tun and br-prv,are patched into another OpenStack bridge, called br-int. I wasn’t actuallysure about whether to tinker with this bridge, and wondered what datapathit was using.Then, I realized there is a parameter in theopenvswitch_agent.ini file, which I will list here:# OVS datapath to use. 'system' is the default value and corresponds to the# kernel datapath. To enable the userspace datapath set this value to 'netdev'.# (string value)# Possible values:# system - <No description provided># netdev - <No description provided>#datapath_type = systemdatapath_type = netdevSo in tinkering with this, what I realized, is that when you set thisdatapath_type to system or netdev, it will adjust the br-int bridge to thatdatapath type.So here is my question. How can I launch a non-DPDK VM, ifall of the bridges are using the netdev datapath type?Here is anotherquestion. What if one of the flavors don’t have the largepages property seton them? I assumed OpenStack would revert to a system datapath and not useDPDK for those VM interfaces. Well, I found out in testing, that is not thecase. If you set all your bridges up for netdev, and you don’t set theproperty on the Flavor of the VM (largepages), the VM will launch, but itsimply won’t work.Is there no way, on a specific Compute Host, to supportboth DPDK (netdev datapaths) and non-DPDK (system datapaths)?Either on a VMinterface level (VM has one interface that is netdev DPDK and another thatis system datapath non-DPDK)?Or on a VM by VM basis (VM 1 has 1 or morenetdev datapath interfaces and VM 2 has 1 or more system datapathinterfaces)?Am I right here? Once you set up a Compute Host for DPDK, it’sDPDK or nothing on that Compute Host? (edited)

How to config DPDK compute in OVN
by dangerzone ar 22 Apr '25

Hi....as far I understand ovs does support dpdk compute to be deployed. I'mreferring 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 networkingopenstack? 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

Hello Glance users,The Glance project team wants to determine whether anyone is using the glance-scrubber utility [0]. If not, we are thinking of deprecating it this cycle to be removed in the appropriate future cycle.If you have not previously heard of the glance-scrubber, that's most likely because it's only useful for particular deployment configurations of which yours is not one. See the doc [0] for details if you are curious.Our suspicion is that the glance-scrubber may have outlived its usefulness for modern OpenStack configurations. (The last time I remember it being discussed at a PTG was during the snowstorm in Dublin, which I believe was the Rocky development cycle). On the other hand, the team also has some ideas for improving the scrubber, but there's no point doing that if it's not actually being used in the first place.So if removal of the glance-scrubber would negatively affect you, please respond to this email so we can get some data points.Thanks![0]https://docs.openstack.org/glance/latest/cli/glancescrubber.html

Hi,we have a couple of k8s clusters in our openstack environment (Victoria) and are facing some problems when pods get moved to different worker nodes. The PVCs get stuck in "reserved" state, and they only get attached after resetting the volumes to "available" state. First I thought it was due to the missing multiattach volume type which seems to work fine in our customer's cluster. I also found the "duplicate connector" error messages in the nova-compute.log:> Unable to update attachment.(Invalid volume: duplicate connectors > detected on volumeBut after adding the multiattach volume type and retyping the affected volumes, the PVCs still get stuck in "reserved" state while I don't see any error messages on the hypervisors anymore. So it seems that something has changed/improved, but now I don't have a trace where to look next. Could this be a cinder-csi driver issue or something? Our cinder backend is ceph (Pacific).Not sure which information could help so please ask for anything I can provide. Any pointers are highly appreciated!Thanks!Eugen

Hello Koalas,OpenEuler jobs in master (to be Antelope) are failing for a long time.If no one is interested in maintaining OpenEuler support in Kolla-Ansible - I will propose dropping it’s support on Wednesday Kolla meeting.Best regards,Michal
