I have flashed UbuntuMate on my micro-SD, which could be used to boot my Odroid XU4 board. It works perfectly on the Odroid Board for prototyping but Now I want to boot UbuntuMate from VritualBox on my Mac OS X as well.
I followed this tutorial: http://innov8tiv.com/boot-virtual-machine-usb-virtualbox-guide/ and created .vmdk file to be able to boot from the usb drive (micro-SD attached). But when I am trying to boot from the USB (micro-SD) it is giving me the following error:
VD: error VERR_NOT_SUPPORTED opening image file
Any idea how I can boot UbuntuMate on VirtualBox from my bootable USB (micro-SD)?
P.S. Using -- VirtualBox Graphical User Interface Version 5.2.14 r123301 (Qt5.6.3) Mac Os X: High Sierra
