[ironic] Slight PTG Schedule change
by Jay Faulkner 28 Mar '23

28 Mar '23

Take notice: tomorrow's topic schedule has been changed slightly. We have moved Service Steps and DPU Orchestration conversations up 30 minutes. As mentioned in the other thread ( https://lists.openstack.org/pipermail/openstack-discuss/2023-March/032983.h…) I accidentally booked Firmware Upgrades to two times. This was fortuitous because we needed to add a cross-team item with Keystone. As always, the up to date schedule and notes are here: https://etherpad.opendev.org/p/ironic-bobcat-ptg Thanks, Jay Faulkner Ironic PTL

[all][ptg] Pre-PTG discussion: New Keystone Middleware Feature Supporting OAuth2.0 with External Authorization Service
by Hiromu Asahina 28 Mar '23

28 Mar '23

Hello Everyone, Recently, Tacker and Keystone have been working together on a new Keystone Middleware that can work with external authentication services, such as Keycloak. The code has already been submitted [1], but we want to make this middleware a generic plugin that works with as many OpenStack services as possible. To that end, we would like to hear from other projects with similar use cases (especially Ironic and Barbican, which run as standalone services). We will make a time slot to discuss this topic at the next vPTG. Please contact me if you are interested and available to participate.

[nova] Can OpenStack support snapshot rollback (not creating a new instance)?
by 韩光宇 28 Mar '23

28 Mar '23

Hello, I use Ceph as the storage backend for Nova, Glance, and Cinder. If I create a snapshot for a instance, It create a new image in glance. And I can use the image to create a new instance. This feels to me more like creating an image based on the current state of the VM rather than creating a VM snapshot. I want to ask: 1、Can I create and revert a VM snapshot like I would in virtual machine software? 2、When a VM uses multiple disks/volumes, does OpenStack support taking a snapshot of all disks/volumes of the VM as a whole? 3、Can OpenStack snapshot and save the memory state of a VM? If it is not currently supported, are there any simple customization implementation ideas that can be recommended? Thank you for any help and suggestions. Best wishes. Han

[cinder][PTG] Cinder 2023.2 (Bobcat) Virtual PTG
by Rajat Dhasmana 24 Mar '23

24 Mar '23

Hello Argonauts, We will be conducting cinder virtual PTG for 2023.2 (Bobcat) cycle from 28th March to 31st March, 2023. I've prepared the PTG etherpad[1] with topics day wise. I haven't kept the schedule time bound since some discussions take less and some take more time and in both cases reaching a conclusion is important. There are some events that need to be done on their respective time are as follows: *1) Operator Hour: *We encourage operators to join and tell us about the pain points of cinder so we can improve upon it. Date: Wednesday, 29 March, 2023 Time: 1400-1500 UTC Link: https://bluejeans.com/556681290 *2) Glance Cross Project* Date: Thursday, 30 March, 2023 Time: 1430-1500 UTC Link: https://bluejeans.com/556681290 *3) Nova Cross Project* Date: Thursday, 30 March, 2023 Time: 1600-1700 UTC Link: https://zoom.us/j/96494117185?pwd=NGhya0NpeWppMEc1OUNKdlFPbDNYdz09 (Diablo room) The general information about the PTG is as follows: Date: 28th March to 31st March, 2023 Time: 1300-1700 UTC everyday Link to PTG: https://bluejeans.com/556681290 You can also follow the schedule at https://ptg.opendev.org/ptg.html Note that we have allocated 4 hours each day but it also depends on the number and duration of topics as to how long the PTG will run. If you want to be reminded about a particular topic, please add your IRC nick in the *Courtesy ping list *mentioned after every topic. If you still have topics, please add them to the Planning etherpad[2] and I will see if we can accommodate that into our current schedule. Lastly, we will be cancelling our cinder upstream meeting (Wednesday, 29 March, 1400-1500 UTC) since it overlaps with the PTG. If you still have topics please bring it to the PTG. See you all at the PTG! [1] https://etherpad.opendev.org/p/bobcat-ptg-cinder [2] https://etherpad.opendev.org/p/bobcat-ptg-cinder-planning Thanks Rajat Dhasmana
