virtualbox.org

I'm running VBox 6.0.24 on host Debian 10 Buster. I'm unable to drag files from the host desktop to the android VM even though I have Shared Folders configured in VBox settings to do so. I see that Guest Additions must be installed in order to share folders. When I open Vbox, select the android VM and open it, the android VM opens properly, but it is accompanied by a slew of error messages on the Vbox screen saying "init: Could not find service hosting interface android.hardware...." and "error: rate limit exceeded". If I ignore these error messages and go to Devices > Insert Guest Additions CD Image, I get an error message saying "Could not insert the usr/share virtualbox/VBoxGuestAdditions.iso disk image file into the virtual machine Android." I checked the .iso file folder location and it is there in its entirety. Why can't I install Guest Additions and could someone help me figure out how to accomplish this?

Since there are no Guest Additions for Android I'd say that difficulty installing them is hardly a huge shock.

RTFM, particularly section 4.2. This tells you which guest OS's are supported with Guest Additions.

Ok thanks. I guess I have no choice but to install a VM OS on host Debian 10, then add Guest Additions, then within the VM create another VM, i.e. the genymotion android phone.
