Version-Release number of selected component (if applicable):

libguestfs 1.16.10 from RHEL 6.3 (but we don't think it
is specific to RHEL)

I have asked for the SYSTEM hive from the VM.

Comment 2 Richard W.M. Jones 2012-03-15 12:39:00 UTC

The problem is pretty clear from the SYSTEM hive supplied:
There is no HKLM\SYSTEM\MountedDevices key present at all.
Perhaps sysprep removes this key.

Inspection should be changed so that if this key is missing
it is not an error (but the drive letters will not be populated).
