Hi guys,

New user, non-linux background here.

So i need to deploy a kali linux(64b) installation on several win 7 computers. They are VT capable and are using Virtual Box as local hypervisors.
I installed the latest distribution on a VM, set the root password & completed installation. As a next step, via Virtual Box, I cloned the machine and distributed it on the network.
Ultimately, I added manually the cloned machine to each hypervisor.

The machines boot up but the root's password is not accepted(neither the "default" root password "toor").
I wasn't able to find the reason behind this and right now i've installed each machine from scratch. However I would like to know if this is some sort of limitation of Kali or if I'm missing something.
note: a win clone of win10 works without problems.
Thank you for all your feedback.
