Not too hard to wire up. The trickiest part is realizing that listing children of a snapshot cannot use SNAPSHOT_LIST_ROOTS, and that we overloaded that bit to also mean SNAPSHOT_LIST_DESCENDANTS; we use that bit to decide which iteration to use, but don't want the existing counting/listing functions to see that bit. * src/conf/domain_conf.h (virDomainSnapshotObjListNumFrom) (virDomainSnapshotObjListGetNamesFrom): New prototypes. * src/conf/domain_conf.c (virDomainSnapshotObjListNumFrom) (virDomainSnapshotObjListGetNamesFrom): New functions. * src/libvirt_private.syms (domain_conf.h): Export them. * src/qemu/qemu_driver.c (qemuDomainSnapshotNumChildren) (qemuDomainSnapshotListChildrenNames): New functions.
