I've removed Pike and Queens from this since those are lower priority since https://review.openstack.org/#/q/Id3c74c019da29070811ffc368351e2238b3f6da5 hasn't landed on those branches.

The flavors and the instances needed to be upgraded with the correct resource class. This was done by an online data migration. Looking into Rocky code: ironic.driver._pike_flavor_migration There is also an offline data migration using nova-manage. These migrations added the node resource class into instance_extra.flavor however I don't see that they also included the default resource classes (VCPU, MEMORY_MB, DISK_GB) set to 0. Looking into Rocky code there is also a TODO in _pike_flavor_migration: "This code can be removed in Queens, and will need to be updated to also alter extra_specs to zero-out the old-style standard resource classes of VCPU, MEMORY_MB, and DISK_GB." Currently all my Ironic instances have the correct node resource class defined, but "old" instances (created before the flavor migration) don't have VCPU, MEMORY_MB, DISK_GB set to 0, in instance_extra.flavor. In Rocky the resource tracker raises the following message: "There was a conflict when trying to complete your request.\n\n Unable to allocate inventory: Inventory for 'VCPU' on resource provider XXXX invalid. ", "title": "Conflict" because it tries to update the allocation but the inventory doesn't have vcpu resources. --- As mitigation we now have: "requires_allocation_refresh = False" in the Ironic Driver.
