[libvirt] [PATCH 3/4] Support bond interfaces attached to bridges in interface xml.

This was accomplished in xml parsing by doing away with the stripped-down virInterfaceBareDef object, and just always using virInterfaceDef, but with restrictions in certain places (eg, the type of subordinate interface allowed in parsing depends on the parent interface). xml formatting was similarly adjusted. In addition, the formatting functions keep track of the level of interface nesting, and insert extra leading spaces on each line accordingly (using %*s). The only change in formatted xml from previous (aside frmo supporting new combinations of interface types) is that the subordinate ethernet interfaces take up 2 lines rather than one, eg: <interface type='ethernet' name='eth0'> </interface> instead of: <interface type='ethernet' name='eth0'/> --- src/conf/interface_conf.c | 362 +++++++++++++++++++-------------------------- src/conf/interface_conf.h | 13 +-- 2 files changed, 156 insertions(+), 219 deletions(-) diff --git a/src/conf/interface_conf.c b/src/conf/interface_conf.c index d7821e7..6efc8aa 100644 --- a/src/conf/interface_conf.c +++ b/src/conf/interface_conf.c @@ -39,21 +39,18 @@ VIR_ENUM_IMPL(virInterface, VIR_INTERFACE_TYPE_LAST, "ethernet", "bridge", "bond", "vlan" ) +static virInterfaceDefPtr +virInterfaceDefParseXML(virConnectPtr conn, + xmlXPathContextPtr ctxt, int parentIfType);
