[Neutron] Bug deputy report Jan 19-26
by Jakub Libosvar 26 Jan '26

26 Jan '26

Hi all, I was the bug deputy for the last week. There are two undecided bugs, one proactive from the Nova team and one that might already be solved in master, would be good to discuss at the next team meeting. Here is the full report: Medium ------ * Ensure no RPC clients are instantiated if ``rpc_workers=0`` https://bugs.launchpad.net/neutron/+bug/2139063 * [OVN] ``LogicalRouterPortEvent`` should discard routers not handled by Neutron API https://bugs.launchpad.net/neutron/+bug/2139067 Rodolfo already proposed a patch: https://review.opendev.org/c/openstack/neutron/+/974709 Low --- * Remove neutron-ovn-db-sync-util and OVNDbMonitor functional tests using various connection types https://bugs.launchpad.net/neutron/+bug/2139064 Slawek already proposed a patch: https://review.opendev.org/c/openstack/neutron/+/974691 Undecided --------- * Broken connectivity to external gateways for baremetal nodes https://bugs.launchpad.net/neutron/+bug/2138941 This one is actually fixed in master and we can discuss if it can be closed. * Live migration or any host update operation may require resetting NVRAM https://bugs.launchpad.net/neutron/+bug/2139077 This is a proactive report and it’s still not clear if there is any need from Neutron.

[nova] Ephemeral storage potential features
by Karol Klimaszewski 26 Jan '26

26 Jan '26

Hello, In my company (CloudFerro) we have developed two features related to nova ephemeral storage (with libvirt virt driver) - "SPDK-based ephemeral storage backend" and "Multiple ephemeral storage backend handling" (both described below). Would these features be appropriate to be added to upstream? If yes, then should I start with creating a blueprint and proposing a spec for each of them so it is more clear what we want to introduce? Of course not both at once, since there is some code that makes one work with the other. For us it would probably be best if we upstreamed "SPDK-based ephemeral storage backend" first and then upstreamed "Multiple ephemeral storage backend handling" Description of SPDK-based ephemeral storage backend: We add a new possible value for [libvirt]/images_type in nova.conf: spdk_lvol. If this value is set then local disks of instances are handled as logical volumes (lvols). of locally run SPDK instance (on the same compute as VM). See https://spdk.io/doc/logical_volumes.html#lvol for docs on this subject. These are essentially a part of local NVMe disk managed by SPDK. We create and manage those lvols by making calls from nova-compute to SPDK instance with RPC (https://spdk.io/doc/jsonrpc.html) using provided python library (https://github.com/spdk/spdk/blob/master/python/README.md) We attach those lvols to instances by exposing them as vhost-blk devices (see https://spdk.io/doc/vhost.html) and specifying them as disks with source_type='vhostuser'. This method of exposing NVMe local storage allows for much better I/O performance than exposing them from local filesystem. We currently have working: creating, deleting, cold-migrating, shelving, snapshots, unshelving VMs with this storage backend. We don't have live migration working yet but have it in plans. This feature includes changes only to nova. Description of Multiple ephemeral storage backend handling: We add a new configuration option [libvirt]/supported_image_types to nova.conf of nova-compute and change the meaning of [libvirt]/images_type to mean default image type. If libvirt:image_type extra_spec is specified in flavor then VM is scheduled on compute with appropriate image type in its [libvirt]/supported_image_types. We use potentially multiple DISK_GB resource providers and construct appropriate request groups to handle this scheduling. This spec is also used to fill driver_info.libvirt.image_type field of BDMs with destination_type=local of this VM. (driver_info is new JSON serialized field of BDM) Then in compute if BDM specifies this field we use its value instead of [libvirt]/images_type to decide on imagebackend to use for it. This method of handling multiple backends only works after being enabled by administrators by setting libvirt:image_type on all their flavors and running nova-manage commands that update existing VMs. Without enabling everything works as it was before. This feature includes changes to nova and some new traits in os-traits (One per possible value of [libvirt]/images_type + one extra) Best regards, Karol Klimaszewski

[Neutron] VPNaaS one to many subnets
by Robert N 23 Jan '26

23 Jan '26

Dear Community, I'm trying to configure VPNaaS between 2 sites, both sites have one openstack subnet with 2 networks. left side. subnet 192.168.0.0/24 gw 192.168.0.1 subnet 172.0.0.0/16 - the scope for this is just local network, it doesn't have to be routed outside. this subnet is broke into /24 subnets and assigned to differnt nodes on the network, and they are reachable with explicit routes on the router. It's basically a kubernetes pod network, and the routes are managed by openstack-cloud-controller-manager. right side subnet 192.168.1.0/24 gw 192.168.1.1 subnet 172.1.0.0/16 I need connectivity between the 2 sites on both layers 192.... and 172... so I tried to endpoint groups, a local of type subnet and a peer of type cidr with the cidrs `192.168.0.0/24,172.0.0.0/16` and respectively ` 192.168.1.0/24,172.1.0.0/16`. With this setup the vpn connection doesn't come up. If I create the peer cidr with only one cidr `192.168.0.0/24` and respectively `192.168.1.0/24` the vpn connection becomes active and works as expected for the 192... netowrks. I tried adding manually the routes for the 172.0.0.0/16 on one side and 172.1.0.0/16 o the other side with to the same gateway `169.254.0.2` but it doesn't work. I'm wondering how could I configure the VPN to have both networks routed 192... and 172... Appreciating any input on the topic. Cheers, Robert

[kolla] Dropping support for building and deploying InfluxDB
by Michał Nasiadka 22 Jan '26

22 Jan '26

Hello Koalas, Kolla project plans to drop support for InfluxDB, given that current version supported by the project is v1, which is in End of Life state. We haven’t seen any interest in introducing v2 support and given that the core team also has no interest in doing that - we’re dropping support. See https://review.opendev.org/q/topic:%22kolla_drop_influxdb%22 Michal
