Examples with Image org.ovirt.engine.core.common.businessentities.storage.Image used on opensource projects

Example 1 with Image

use of org.ovirt.engine.core.common.businessentities.storage.Image in project ovirt-engine by oVirt.

the class RemoveSnapshotSingleDiskCommandBase method handleBackwardMerge.

private void handleBackwardMerge(DiskImage topImage, DiskImage baseImage, DiskImage imageFromVdsm) {
    // For backwards merge, the prior base image now has the data associated with the newer
    // snapshot we want to keep.  Re-associate this older image with the newer snapshot.
    // The base snapshot is deleted if everything went well.  In case it's not deleted, we
    // hijack it to preserve a link to the broken image.  This makes the image discoverable
    // so that we can retry the deletion later, yet doesn't corrupt the VM image chain.
