after command init 6, generate core dump and duplicate UUID

[maximilian]

Hello, unfortunately I answered yes to upgrade on Virtualbox 5.0.12 hang on create new disk, resolved on 5.1.19 and install it. Virtualbox 5.1.19 corrupted 6 Guest Machine and install 5.1.51-114298

Now it is not present later, he returned to version 5.0.12 that worked well? I honestly did not know if the problem is in virtualbox core or in the host machine, with win7.

the problems that I see right now are:

• Duplication of Guest UUID that worked and you can not run the start
• see attach: although, on this generated core dump I found something and I just solved will update

Regards, Massimo
