Re: [libvirt] [PATCH] lib: snapshot: Explain that only one layer of images is inserted

When creating a snapshot with _REUSE_EXTERNAL when the pre-created image does not directly link to the current active layer libvirt would re-detect the backing chain incorrectly and it would not match with qemu's view. Since the configuration is an operator mistake, document that only the top layer image gets inserted. --- src/libvirt-domain-snapshot.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
