How can I specify a helm override to configure nova PCI alias when there are multiple aliases? I haven't been able to come up with a YAML compliant specification for this.
Are there other alternatives to be able to specify this as an override? I assume that a nova Chart change would be required to support this custom one-alias-entry-per-line formatting.
Any insights on how to achieve this in helm are welcomed.
<snip>
The following nova configuration format is desired, but not as yet supported by nova: [pci] alias = [{dict 1}, {dict 2}]
The following snippet of YAML works for PCI passthrough_whitelist, where the value encoded is a JSON string:
conf: nova: overrides: nova_compute: hosts: - conf: nova: pci: passthrough_whitelist: '[{"class_id": "030000", "address": "0000:00:02.0"}]'
<snip> I played around with the code as it stands, and I agree there doesn't seem to be a way around having to specify the alias key multiple times to get multiple aliases. Lacking some fancy way to make YAML understand a dict with repeated keys ((how) do you handle HTTP headers?), I've hacked up a solution on the nova side [1] which should allow you to do what you've described above. Do you have a way to pull it down and try it? (Caveat: I put this up as a proof of concept, but it (or anything that messes with the existing pci passthrough mechanisms) may not be a mergeable solution.) -efried [1] https://review.openstack.org/#/c/635191/
