* src/conf/domain_conf.h (virDomainSmartcardType): New enum. (virDomainSmartcardDef): New struct. (virDomainDef): Include smartcards. (virDomainSmartcardDefIterator): New typedef. (virDomainSmartcardDefFree, virDomainSmartcardDefForeach): New prototypes. * src/conf/domain_conf.c (virDomainSmartcard): Convert between enum and string. (virDomainSmartcardDefParseXML, virDomainSmartcardDefFormat) (virDomainSmartcardDefFree): New functions. (virDomainDefParseXML): Parse the new XML. (virDomainDefFormat): Convert back to XML. (virDomainDefFree): Clean up. (virDomainDeviceInfoIterate): Iterate over passthrough aliases. * src/libvirt_private.syms (domain_conf.h): New exports. * cfg.mk (useless_free_options): List new function. --- cfg.mk | 1 + src/conf/domain_conf.c | 224 ++++++++++++++++++++++++++++++++++++++++++++++ src/conf/domain_conf.h | 40 ++++++++- src/libvirt_private.syms | 4 + 4 files changed, 268 insertions(+), 1 deletions(-)
