The changes in Ie27dbbc510c73c685b239a9be4af2700a0eb42f0 did not appear to fix the handling of the nova pci_* params. The config being written to nova.conf remains in the ListOpt format. As support for MultiStrOpt was added to nova_config in I6be7bb4cea1906bd98c513bd2d01153e4643e3ac we just need to pass an array of strings to nova_config to set these MultiStrOpt params. Nova expects the string values to be JSON encoded so that is what the parser function now returns. This function has also been renamed from 'check_array_of_hash' (which it never did) to 'to_array_of_json_strings'. The acceptable input formats are a JSON array of objects or a puppet Array of Hashes. Perviously a "JSON with single quotes" format was used but should now be considered deprecated as it could corrupt data. This also removes any pci_alias entries from nova.conf when the param is not set. Change-Id: Ida3ecab717bc3113ba23553c559263f35c49c46a Closes-bug: #1696955
