- External snapshot metadata redefinition is fixed
- Attempting to use VIR_DOMAIN_SNAPSHOT_CREATE_REDEFINE to reinstate the metadata describing an external snapshot created earlier for an offline domain no longer fails.
- v3.5.0 (2017-07-04)
- qemu: snapshot: retrieve image metadata from user provided files
- Disk images of an external snapshot created with VIR_DOMAIN_SNAPSHOT_CREATE_REUSE_EXT flag specified would not be scanned for metadata after recent changes. The metadata is necessary to allow keeping relative paths between images when doing a block-commit.
