[ironic] Call to action: Fix SNMP driver, or it may have to go
by Jay Faulkner 07 Apr '25

07 Apr '25

Hey all, So as many of you know, Ironic has had a driver for supporting SNMP-based PDUs (where you use an SNMP command to power on/off servers) for a while. This driver heavily uses pysnmp, a library created by a late Ironic contributor that was taken over by another company afterwards. This library is good, but is extremely fast moving and difficult for Ironic developers to keep up with. In fact, right now, both our SNMP-BMC emulator (virtualpdu) and Ironic are stuck using pysnmp-lexstudio, an old version of pysnmp which is now preventing other packages, e.g. pyasn1, from being upgraded. This is unsustainable in the long term, and it's been in this state for a while already. If you are an operator or organization that utilizes the SNMP driver, you need to rapidly find another method to manage power on your servers or help the Ironic developers maintain the SNMP driver -- at a minimum getting us onto the new pysnmp library (not a small undertaking; it's unexpectedly difficult). It's my intention to propose to the Ironic team that we mark this driver as unsupported and remove any remaining functional testing for it in anticipation of fully removing the driver in a future cycle. I do not want to take this action, but I'd rather have a driver removed from Ironic than one that's not going to work or hold the rest of the OpenStack requirements back. If you use this driver, please get in contact with the Ironic team if you have any resources to help with this migration. Feel free to use me-directly as a contact point if you're unsure where to start. Thanks, Jay Faulkner Ironic Security Liason

[neutron] Neutron sriov vf-lag port binding
by Serhat Rıfat Demircan 07 Apr '25

07 Apr '25

Hello everyone, I have tested sriov with Connectx-5 cards, it works well but I also want to try ovs with hardware offload feature. I believe I have properly configured pf, vfs and bonding :). PF’s are working in switchdev mode (I have followed stackhpcs article[1]). Unfortunately, I see port binding errors when creating instances. I have created a vlan provider network and a port with vnic_type=direct under that network. I am trying to create instance with that port. nova-compute.log > 2025-04-04 17:37:28.014 7 ERROR nova.compute.manager [instance: > bf8408e8-20a9-4963-9e50-033e54aba9fe] nova.exception.PortBindingFailed: > Binding failed for port 6cbd8181-5707-4349-9fa0-c35e7370bfcd, please check > neutron logs for more information. neutron-server.log > 025-04-04 17:37:27.000 25 DEBUG > neutron.plugins.ml2.drivers.mech_sriov.mech_driver.mech_driver > [req-ff074be0-e410-4df8-8938-7e2b59a84bfd > req-d9bffb08-7e74-4976-b3ae-8cb544ec71f5 fbbdf9e30cad498180c3b637d1bba6d9 > 3e7a1867f1c24a158b4bb2d2f3f68b9c - - default default] Refusing to bind due > to unsupported vnic_type: direct with switchdev capability bind_port > /var/lib/kolla/venv/lib/python3.10/site-packages/neutron/plugins/ml2/drivers/mech_sriov/mech_driver/mech_driver.py:130 neutron/plugins/ml2/drivers/mech_sriov/mech_driver/mech_driver.py > if (vnic_type == portbindings.VNIC_DIRECT and > 'switchdev' in capabilities): > LOG.debug("Refusing to bind due to unsupported vnic_type: %s " > "with switchdev capability", > portbindings.VNIC_DIRECT) nova.conf > [pci] > passthrough_whitelist = [{"physical_network": "physnet5", "devname": > "ens10f0"},{"physical_network": "physnet6", "devname": "ens10f1"}] [sriov_nic] physical_device_mappings = physnet5:ens10f0,physnet6:ens10f1 Is vnic_type=direct wrong if switchdev in capabilities or is this a configuration issue?

[manila]NFS-Ganesha exports
by Mikhail Okhrimenko 06 Apr '25

Hello community, Trying to setup the Manila version of Caracal with NFS-Ganesha backend. Ganesha version 4.0 is deployed using ceph orch in a ceph cluster version 17. Backend configuration in manila.conf [ganesha_nfs] driver_handles_share_servers = False share_backend_name = ganesha_nfs Share_driver = manila.share.drivers.cephfs.driver.CephFSDriver cephfs_protocol_helper_type = NFS cephfs_conf_path = /etc/ceph/ceph.conf cephfs_auth_id = manila cephfs_cluster_name = ceph cephfs_filesystem_name = {{ cephfs_filesystem_name }} cephfs_nfs_cluster_id = {{ cephfs_nfs_cluster_id }} I see the subvolume being created in ceph ceph fs subvolume ls <volume_name> but no export ceph nfs export ls <cluster_id> what am I doing wrong? what am I missing? in the manila-share logs I see a request to create a subvolume, but I don't see a request to create an export, for some reason manila doesn't even try to create an export

[nova] vGPU not attached to VM using Cyborg with OpenStack Caracal
by ts.jung＠okestro.com 04 Apr '25

04 Apr '25

Hello, I'm facing an issue with vGPU assignment through Cyborg in OpenStack Caracal. Although Cyborg reports that the ARQ is bound successfully, the vGPU device is not attached to the VM in Nova. - Environment: OS: Ubuntu 22.04.3 LTS Kernel: 5.15.0-78-generic Nova API: 29.2.0 Cyborg API: 14.1.0.dev1 GPU: NVIDIA A100 PCIe 40GB - Device Profile: openstack accelerator device profile list +--------------------------------------+------+-----------------------------------------------------------------------------+ | uuid | name | groups | +--------------------------------------+------+-----------------------------------------------------------------------------+ | 8425925f-7a3c-4336-8a1c-270f481a28ae | vgpu | [{'resources:VGPU': '1', 'trait:CUSTOM_NVIDIA_20F1_A100_1_5C': 'required'}] | +--------------------------------------+------+-----------------------------------------------------------------------------+ Flavor: openstack flavor show vgpu --column properties +------------+-----------------------------+ | Field | Value | +------------+-----------------------------+ | properties | accel:device_profile='vgpu' | +------------+-----------------------------+ Result After VM Creation: openstack accelerator arq list +--------------------------------------+------+-----------------------------------------------------------------------------+ | uuid | name | groups | +--------------------------------------+------+-----------------------------------------------------------------------------+ | 8425925f-7a3c-4336-8a1c-270f481a28ae | vgpu | [{'resources:VGPU': '1', 'trait:CUSTOM_NVIDIA_20F1_A100_1_5C': 'required'}] | +--------------------------------------+------+-----------------------------------------------------------------------------+ ARQ shows Bound with an attach_handle_type of MDEV, but the GPU device is not visible inside the VM. mdevctl list # Shows UUID and mdev type virsh dumpxml instance-xxxx # No mdev device listed Logs (Summary) Cyborg logs indicate ARQ binding was successful and attach handle allocated (MDEV). Nova-compute logs show: Ignoring accelerator requests for instance ... Supported Attach handle types: {'PCI'}. But got these unsupported types: {'MDEV'}. Question. Is there something I’m missing in the integration between Cyborg and Nova for MDEV attach_handle_type? It seems like Nova is not yet supporting MDEV, even though Cyborg bound the ARQ correctly. Any suggestions or known workarounds would be appreciated. Thank you!

[Octavia] Active/Standby with AZ
by Vincent Godin 04 Apr '25

04 Apr '25

Hello, To address the Octavia and Cinder backend mismatch, I'm going to temporarily create a Cinder backend stretched across all three AZs. Now I have another question: is it possible to use Octavia AZs to set up an active/standby load balancer so that the active load balancer is on one AZ and the standby load balancer is on another one ? Of course, the network is stretched across all three AZs, so the VRRP mechanism is possible. Vincent
