Description of problem: When incremental backup introduced as a tech preview there was a known libvirt bug 1779893 for doing live disk migration when the VM contains also incremental backups. In this case, after live storage migration, all the bitmaps go lost, and the next backup will have to be a full back. Version-Release number of selected component (if applicable): 4.4.1 How reproducible: 100% Steps to Reproduce: 1. Create a VM with disks 2. Run the VM 3. Create an incremental backups for the VM 4. Move the VM disks to another storage domain 7. Create another incremental backup for the VM Actual results: All the the incremental backup bitmaps got lost. Expected results: Incremental backup bitmaps should be kept so a new incremental backup can be taked after the live storage migration operation. Additional info:
Verified on rhv-4.4.3-8 according the steps from description.
