Hi Stackers! I would like to sync about the planned timeline of dropping eventlet support from OpenStack / Oslo. Nova definitely needs at least the full 2026.1 cycle to have a chance to transform the nova-compute service. But this plan already feels stretched based on the progress in the current cycle. So being conservative means we need the 2026.2 cycle as a buffer. Nova would like to keep a release where we support both eventlet and threading in parallel. So that operators can do the switching from eventlet to threading outside of the upgrade procedure. (This was an explicit request from them during the PTG). So 2026.2 could be that version where nova fully supports both concurrency mode, while eventlet can be marked deprecated. Then the 2027.1 release could be the first release dropping eventlet. However we need to align with the SLURP upgrade as well. 2026.1 is a SLURP. But in that release Nova might not be ready to have all services running in threading mode. So the 2026.1 - 2027.1 SLURP upgrade would force the operators to change the concurrency mode during the upgrade itself. I see two ways forward: * A) We say that operators who want to do the concurrency mode change outside of an upgrade could not skip the 2026.2 release, i.e. they cannot do SLURP directly from 2026.1. to 2027.1. * B) We keep supporting the eventlet mode in the 2027.1 release as well and only dropping support in 2028.1. What do you think? Cheers gibi
