Bug#600177: virtualbox-ose: out of disk while merging a snapshot destroys the disk image
Package: virtualbox-ose
Version: 3.2.8-dfsg-2
Severity: grave
Justification: causes serious data loss
If you elect to merge the current state of a differentiating disk image into
the base (deleting a snapshot) and run out of disk space on the host
filesystem while merging, the resulting image will be corrupted.
I happened to look at the ~/.VirtualBox/VDI and
~/.VirtualBox/Machines/${machine}/Snapshot directories before trying to
continue, they did have both the base image and the differential one, so at
this point I guess it would be recoverable by simply restarting -- sectors
that were already overwritten by the new values would be overwritten with
the same data again. However, when retrying the merge, VirtualBox started
merging a second disk (the virtual machine in question had two) and deleted
the first differential image.
