I tried it with one machine and I have seen that after import the harddisk file is not vdi any more - got vmdk.

Although I do plain backups (which indeed helped me here - btw also update your ~/.virtualbox folder), I could not live without snapshots. Problem is that the copy operations take so much time and I need to put them on external HDs because don't have enough place on my internal HD for all the VMs.
Restoring a snapshot on the other hand is fast.
What I did (so far only for machines without existing snapshots - don't know if it works also in those cases):
- I took notes about the machine settings (remember to note the MAC addresses of attached network interfaces) and removed them from the listed machines (only remove - not delete the files).
- Then I moved the vdi into the appropriate subfolder of the VM (because of old VirtualBox versions stored the vdi not in the vm subfolder) and deleted the old configuration files there.
- Went to File->Virtual Media Manager and removed the vdi, which now not found any more (because of old VirtualBox versions stored the vdi not in the vm subfolder).
- Then I created a new virtual machine using exactly the same settings and chose to use an existing harddisk (vdi) file instead of creating a new one.
Now I have all config files in new style and hope this will prevent from the problem in the future.

Precisely, which is IMHO why export/import should not be used for backup. The whole idea of a backup is to preserve a working installation - the last thing you want to do during the backup procedure is
change that working installation.

Oh? I and many others manage to live without snapshots, rather well. Why not you?
A clone does everything a snapshot does, while being more space efficient (*) and less easily corrupted. The only thing cloning lacks is direct support in the GUI, which I see is being addressed in the new 4.1.0 beta.
(*) the small initial size of a snapshot is quickly a distant memory, and unlike with clones the earlier incarnations of the current snapshot can't be hived off to secondary storage.

Hi all,
Same problem for me. I confirm it happens when one upgrades virtualbox
. I have spent a lot of time to try to recover by playing with the xml but I failed and I am very upset
. Since I have to fully re-install my VM, I take the opportunity to switch to qemu. I don't know if it is better, but it calms me
.
This bug is not acceptable from a company like sun
Sorry to be so negative.
