Not suitable for operation in a virtual environment (Virtual Box)

Have the unit for some time with Banco ALF in use.
The software runs because of the security in its own virtual machine under Virtual Box.
In principle, the function is ok and the readers of the VM can be assigned.

Unfortunately, the computer crashes completely when he wants to go into standby.
It can be reactivated only by power off again.

The service of Reiner SCT said it only briefly:
"The reader is not advertised for virtual environments"
There is no interest to find the error.

I'm certainly not the only one who does not want to do security-related issues in the normal work environment, I think this should be known.

I now known another reader.
Let's see if I have better luck there.
