[ovirt-users] manually merging thin provisioned Ovirt Images

Hi, accidently, i delete the wrong live snapshot of a Virtual Machine. Which whouldnt be that big deal, since Filer Snapshots are created every hour. But... after pulling out the qcow Files of the VM, i am confronted with several files. - the biggest one, which is most likely the main part from what i was able to investigate with qemu-img - several smaller files, which seem to contain the delta - so i expect this files be the live snaps of the vm could anyone point me into a direction to: - push the restored main image file + snapshot files back into ovirt (if its hacky, ok..) or - how to find out which snapshot files need to be merged into the main qcow image to get the latest state for option 2, importing a single qcow image is imho no big deal (virt-v2v). but how the heck do i find out in which order / which files needs to be merged ? Thanks! Juergen
