Release v1.1.0 "solves" immutable must have randomly generated names" but will disconnect nova-compute from MQ
by Stefan Hoffmann Jan. 29, 2026

Jan. 29, 2026

Hi, regarding the immutable must have randomly generated names issue: The issue is "solved" in the latest release v1.1.0 BUT if a new compute- node with same name got created, the change will interrupt connectivity to MQ of the nova-compute POD.[1] As the nova-operator recreates the nova-compute-node, a new MQ user with the same username (but different resource name) get's created and than we have 2 MQ users one old "failing" one new. With rolling out [2] the old one can get deleted, but as the username at MQ is the same, the new one don't work for the nova-compute node anymore, till infra-operator recreates the user. So [2]will lead to an interruption of nova-compute MQ connectivity. One "solution" would be to delete the finalizer for all MQ users stuck in immutable-State before rolling out the release. Or you hope, no actions are done to our OpenStack, till the MQ user got updated.

Broken rolling release 0.20251212.0-rolling.T112342.g9c644a7aea39
by Stefan Hoffmann Jan. 8, 2026

Jan. 8, 2026

Hi, the releases 0.20251212.0-rolling.T112342.g9c644a7aea39 and newer are broken with VM action fails due to service_token_roles_required=true at neutron (and other services). But neutron doesn't has the nova-compute role as allowed service-token-role in it's config[1]. So don't roll it out to your neutron and barbican operator. Currently there is no stable release with this bug. There is already a fix[2] in creation.
