Cyborg nova reports mdev-capable resource is not available

Hi Cyborg Team! Karl from Helm Team. When creating a VM with the correct flavor, the mdev gets created by cyborg agent and I can see it in the nodedev-list --cap mdev. However Nova then fails with: nova.virt.libvirt.driver [<removed>- - default default] Searching for available mdevs... _get_existing_mdevs_not_assigned /var/lib/openstack/lib/python3.10/site-packages/nova/virt/libvirt/driver.py :8357 2023-09-21 14:34:47.808 1901814 INFO nova.virt.libvirt.driver [<removed> - - default default] Available mdevs at: set(). 2023-09-21 14:34:47.809 1901814 DEBUG nova.virt.libvirt.driver [<removed> - - default default] No available mdevs where found.

Hi openstack community, I have deployed Multinode cluster of Openstack through kolla-ansible zed release. The problem I am facing is instances created cannot pick any Ip addresses from the assigned networks which I have created provider and self-service flat network type. Hence, I may not be able to ping and ssh instance from the controller node and these instances won’t be able to connect to the internet. Can anyone guide me how to resolve this issue by pinpointing the initial network configurations settings. -----Original Message----- From: Asma Naz Shariq <asma.naz(a)techavenue.biz> Sent: Wednesday, December 6, 2023 10:42 AM To: 'openstack-discuss(a)lists.openstack.org' <openstack-discuss(a)lists.openstack.org> Subject: RE: openstack-discuss Digest, Vol 62, Issue 5 Netwok Configuration Isssue | Urgent Hi openstack community, I have deployed Multinode cluster of Openstack through kolla-ansible zed release.

For example, if they create a server from an image with long metadata values and then create an image (snapshot) from that server, the new image gets the same metadata parameters as the original image but truncated to 255 chars. Thinking from the perspective of a Openstack user (that does not care what particular service implements what) it would be nice if there was some kind of global policy regarding this. As the shortest length supported right now is nova's, a simple (but maybe not the best?) solution would be to adapt to that length everywhere.

[Neutron] - Getting bridge_name of the port from Java sdk
by Mahudeeswaran Palanisamy 07 Dec '23

07 Dec '23

Hi All, Looks like as part of below commit, bridge_name info has been removed from port binding vif_details dictionary. Is there any way that we can get the bridge_name info of a port? As far as checked we can get this info by checking if port UUID is part of “ports” array in “sudo ovs-vsctl list br” output. But there is no equivalent way to get from Java SDK. https://github.com/openstack/neutron/commit/569bafbbd5f90a458d781f1e49f099f… Thanks, Mahudees This message may contain confidential and privileged information.

For example, if they create a server from an image with long metadata values and then create an image (snapshot) from that server, the new image gets the same metadata parameters as the original image but truncated to 255 chars. Thinking from the perspective of a Openstack user (that does not care what particular service implements what) it would be nice if there was some kind of global policy regarding this. As the shortest length supported right now is nova's, a simple (but maybe not the best?) solution would be to adapt to that length everywhere.

Where might a find the data model for neutron database.
by Gautam Thaker 07 Dec '23

07 Dec '23

I am trying to understand all the tables (including references from one table to another) that are in a standard/typical neutron instance in a standard openstack environment. Where might I find this? I understand underlying relational tables are used mainly by ORM in python using SQLAlchemy. So details/diagrams at either tables or ORM level are welcome.

[Glance] Deprecating Cachemanage Middleware
by Pranali Deore 07 Dec '23

07 Dec '23

Hello Everyone, We have also discussed during Caracal PTG about the deprecation of cachemanage middleware since Cache operations (CR(u)D) is now part of glance API, even though we need to depend on cache middleware to enable it. There are two middlewares related to caching, one is `cache` and other is `cachemanage` and we can now get rid of `cachemanage` middleware and glance-cache-manage command line utility. In this cycle we are going to deprecate cachemanage middleware and api pipeline `keystone+cachemanage` (defined in glance-api-paste.ini) and `glance-cache-manage` command line utility. A deprecation warning message will be added to each command of `glance-cache-manage` utility as well as during initialization of `cachemanage` middleware. The spec-lite has been submitted for the same [1] Please let us know if you have any comments/suggestions on the plan above.

[Glance] Deprecating Location Startegy
by Pranali Deore 07 Dec '23

07 Dec '23

Hello Everyone, Glance core team have discussed and decided during Caracal PTG[1] about the deprecation of location strategy since in Bobcat we added support for the weighing mechanism to glance store[2]. To use this new feature we decided to deprecate location strategy in this cycle and remove it in 'D' (2024.2) development cycle[3]. In this cycle we are going to deprecate following configuration options related to location strategy: * location_strategy * store_type_preference Also a warning message regarding deprecation will be added to`location_order` and `store_type` strategy module during the initiation phase. Please let us know if you have any comments on the plan above.

[openstack-ansible] overriding host vars for compute_hosts
by pi3.14＠tuta.io 06 Dec '23

06 Dec '23

Hey folks, Unfortunately, I am not able to specify host specific variables for the compute hosts. I am trying to specify the `nova_user_ssl_*` variables for each compute node. When these variables are specified in `user_variables.yml` and then specified in `openstack_user_config.yml`, they don't actually end up overriding the variables. But they are recognised correctly in `openstack_inventory.json`. When I remove the variables from `user_variables.yml`, everything works correctly. Is it not possible to specify general variables in `user_variables.yml` and then overwrite them in `openstack_user_config.yml`? Example for `openstack_user_config.yml` (same Problem when using `host_vars` instead of `container_vars`): ``` compute_hosts: compute1: ip: 192.168.1.2 container_vars: nova_user_ssl_cert: "/path/to/cert1" nova_user_ssl_key: "/path/to/key1" nova_user_ssl_ca_cert: "/path/to/ca1" ``` thanks Roby
