I'm trying to get the armbian x86-64 generic image to run in virtualbox. I can successfully convert the *.img file to qcow2 and qemu will run it just fine. However, virtualbox fails to boot it in any format (qcow2, vmdk, vhd, vdi, etc). The grub menu comes up, but when trying to boot Linux then it just sits at a blinking cursor. I've tried converting this a variety of ways, such as using `qemu-img convert`, `vboxmanage convertfromraw` and `vboxmanage convertdd`. None of them yield an image that virtualbox will boot. Has anybody else had success with this, and/or know how to fix it? Thanks.
