[vbox-dev] vhd format not stable?

[Huihong Luo]

Alex,
 
No problem, and thanks for the quick fix.
 
There might be more bugs, I will keep testing.
 
Some times, the error occurs some other places, an error message something like "there are 5993 child disks", the number is kind of random. When this error occurs, the whole disk become inaccessible, and I have to recreate the whole vm.

Hi Huihong,

thanks for the report. This bug is fixed now and should appear soon in
the public svn.

Kind regards,
