There are two *different* things happening: Virtualization and Emulation. *Virtualization* (what VirtualBox generally does), means running a complete machine in a "protectected" state (as a "virtual machine"). This makes uses of special processor instructions and memory management that allows running *on the base processor*, but it a kind of "fun house mirror" way. Emulation is something different. This is a regular program that *emulates* a processor, that is it is a piece of software that does what a piece of hardware does. This is something completely different. It is NOT possible to create a true virtual machine for a *different* processor type on a x86_64 processor. Modern x86_64 processor can run virtual machines that are either x86_64 or i686 processor based. Basically, you cannot have an arm VM running on a x86_64 processor, at least not as a normal VM. In theory, it is possible to write and install an arm *emulator* that will run on a x86_64 processor. But emulating a full-fledged Linux operating system with that emulator is going to be really slow. I don't know if VirtualBox includes a arm emulator or not (I would guess not). > > ________________________________ > From: [email protected] <[email protected]> on behalf > of Brian Tremaine <[email protected]> > Sent: 08 September 2019 17:57 > To: BeagleBoard <[email protected]> > Subject: [beagleboard] Setting up Debian VM for BBB > > Hi All, > I realize my question is VirtualBox related but I'm stuck trying to set up > Debian 'Buster' as my VM for my BBB. > I've gone through several blogs on the setup but it still won't boot Debian. > > My iso image is: debian-10.0.0-armhf-netinst.iso > When I start the VM it drops me into a UEFI shell.
