Reconstruct vbox file?

[mpack]

As it turns out, I have 2 snapshots that reference the same parent UUID - again I do not know how that could have happened.

Nothing unusual in that. Snapshot chains can have branches. If you have two snapshots linking to the same parent then that's a branch.


By the way, you can stop looking in VirtualBox logs for clues to your problem. This has nothing to do with VirtualBox, you have a corrupted filesystem in the guest OS. The VM itself is running fine.

I'm pretty sure I didn't have any branches in my snapshot chain, but I'm obviously lacking in the ability to confirm that now.

I thought that the VM terminating might be due to a file problem as you suggest. I got a glimmer of hope when I saw the error in the log. Oh, well. At least I didn't have anything truly important there. I'll play around with it a bit more.

Thanks to you both for all the input.

Well, you already did pretty much confirm it because of the data you provided: two snapshots with parent links to the same older VDI == a branch. The only other explanation would be that this is a mix of versions of a VM which has been previously backed up, restored, reverted, snapshotted and backed up again etc all without ever wiping obsolete backups.
