Let me try to answer as best as I can.
TerryE wrote:Minette, Thanks for the email and sorry for my tardy response. I've exracted the relevant tags out of the two registry files that you provided. You will see that according to the VBox registry you have one machine and two VDIs registered. Each VDI has a 3 snapshot chain.
This should not be the case. I only did snapshots in the Win XP VDI. If I had understood what snapshots were earlier, maybe I would not have had to reinstall a new VM (Win XP) when my first VM (XP) crashed
I had no snapshots with the initial XP VM, and about 6 snapshots for the Win XP VM.
The story is that after the XP VM crashed, in order to recover my files, I attached the first VM VDI (XP) to the new VM (Win XP) as a second disk.
Then recently I needed to save disk space on my Mac, so I decided to remove the attached XP. vdi disk. Vbox would not let me do it!! I would think it should. So I removed it manually.
I also decided to remove snapshots. I started with the first snapshot. I restarted the VM, and it did restart once. But it did it on my first snapshot, not on the last one. I found that strange. So I logged out, restarted again, and that's when I starting getting the error message.

Maybe because I removed it manually and it could no longer find it. My bad!

Maybe this happened when the system restarted with the 1st (instead of the last) snapshot, duplicating the {f59fe204-ed7c-40fd-9e94-cb79ee5be4c8}.
TerryE wrote:However, because the two snapshot chains have such different time stamps there is something else going on here. The disks are updated pretty synchronously so the pairs for each snapshot should have the same time stamps. Can you give me any possible reason for what is going on here? Have you tried restoring backups? Is your VM supposed to have two disks?
Well, I probably messed up things, but only because Vbox would not do the things it was supposed to do. I was in a bind.
Are you saying the xml cannot be fixed?
What's your take on the chances of recovering my files by installing a new VM and attaching the Win XP VDi as a second disk?
Sorry to say this will be the last time I do it. I have wasted too much time on Vbox. It's too unstable, not finished. Barely Alpha to me. I think VirtualBox is VERY FAR from a sound and stable release. If someone like me - I am no techie but know and understand computers - is having so many problems, then it's not ready for prime-time. I don't understand why it was released to the public, but then there are many things I no longer understand with Sun's decisions nowadays. Sigh!
Terry, thank you for your help. If you feel a reinstall as an attached 2nd drive will recover my files, I'll do it. Don't spend any more time on this issue for me, others need your time.
