Description Keigo Noha 2022-11-09 04:54:02 UTC 
Description of problem:
We found an issue in FFU that instances which have 9+ vpcus and mq is enabled can't do live-migration between OSP16.1 nodes.

The details are written at https://access.redhat.com/solutions/6980544.

The link to the KCS should be written at FFU guide because the environment needs to run overcloud deploy soon after FFU to put the workaround in it.
Comment 1 Keigo Noha 2022-11-14 02:56:11 UTC 
One correction is that applying the following puppet parameter doesn't need to run overcloud deploy command after FFU.

~~~
parameter_defaults:
  ComputeExtraConfig:
    nova::compute::libvirt::max_queues: 8
~~~

This should be configured at upgarde prepare to include it.
