Genymotion Host-only Adapter

Hello. Genymotion cant start without Host-only Adapter. Is it save to use Genymotion as a workstation with first adapter as a whonix network and second adapter as a Host-only Adapter?

I doubt anyone knows.

Genymotion modifies VirtualBox?

Sounds weird at least without understanding the rationale of this.

Unsupported.
