[libvirt] [PATCH 0/5] Handling of undefine and redefine snapshots with VirtualBox 4.2

Hi, This is a serie of patches in order to support undefining and redefining snapshots with VirtualBox 4.2. The VirtualBox API provides only high level operations to manipulate snapshots, so it not possible to support flags like VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY with only API calls. Following an IRC talk with Eric Blake, the decision was taken to emulate these behaviours by manipulating directly the .vbox XML files. The first two patches are some util methods for handling uuid and strings that will be used after. The third patch brings more details in the snapshot XML returned by libvirt. We will need those modifications in order to redefine the snapshots. The fourth patch brings the support of the VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE and VIR_DOMAIN_SNAPSHOT_CREATE_CURRENT flags in virDomainSnapshotCreateXML. The fifth and last patch brings the support of the VIR_DOMAIN_SNAPSHOT_DELETE_METADATA_ONLY flag in virDomainSnapshotDelete. The patches are only for Virtualbox 4.2 Regards, Manuel VIVES Manuel VIVES (5): viruuid.h/c: Util method for finding uuid patterns in some strings virstring.h/c: Util method for making some find and replace in strings vbox_tmpl.c: Better XML description for snapshots vbox_tmpl.c: Patch for redefining snapshots vbox_tmpl.c: Add methods for undefining snapshots src/conf/domain_conf.c | 20 +- src/libvirt_private.syms | 2 + src/util/virstring.c | 129 ++++ src/util/virstring.h | 6 + src/util/viruuid.c | 79 ++ src/util/viruuid.h | 1 + src/vbox/vbox_tmpl.c | 1831 +++++++++++++++++++++++++++++++++++++++++++--- 7 files changed, 1943 insertions(+), 125 deletions(-) -- 1.7.10.4
