[PATCH 24/25] conf: domain: Convert virDomainDiskDef's 'device' to virDomainDiskDevice

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

 



Use the appropriate type for the variable and refactor the XML parser to
parse it correctly using virXMLPropEnum.

Changes to other places using switch statements were required.
