[libvirt PATCH 09/10] conf: move nvram parsing into virDomainLoaderDefParseXML

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The virDomainLoaderDef struct contains fields for both <loader> and
<nvram> elements, so it makes sense to parse them in the same method,
just like we'll format them in the same method.
