Re: [libvirt] [PATCH v7 2/4] Add vbox_snapshot_conf struct

This structure contains the data to be saved in the VirtualBox XML file and can be manipulated with severals exposed functions. The structure is created by vboxSnapshotLoadVboxFile taking the machine XML file. It also can rewrite the XML by using vboxSnapshotSaveVboxFile. --- po/POTFILES.in | 1 + src/Makefile.am | 1 + src/vbox/vbox_snapshot_conf.c | 1383 +++++++++++++++++++++++++++++++++++++++++ src/vbox/vbox_snapshot_conf.h | 100 +++ 4 files changed, 1485 insertions(+) create mode 100644 src/vbox/vbox_snapshot_conf.c create mode 100644 src/vbox/vbox_snapshot_conf.h
