Hello Denis,

it is great to see interest in Xen on ARM and this project!

Unfortunately RPi3 can't run Xen as far as I know due to their non-ARM
interrupt controller without virtualization support. Otherwise it would
have been a good dev board. The BeagleBoard doesn't have processors with
virtualization support so it cannot run Xen either (it needs an Cortex
A7 or A15).

But that's not a problem, because the latest QEMU (2.11) can run Xen
just fine. Build QEMU with --target-list=aarch64-softmmu, then you can
run it with:

qemu-system-aarch64 -machine virt,gic_version=3 \
    -machine virtualization=true \
    -cpu cortex-a57 -machine type=virt \
    -smp 4 -m 2048 \
    -serial stdio -monitor none \
    -bios /path/QEMU_EFI.fd \
    -netdev user,id=hostnet0 -device virtio-net-device,netdev=hostnet0 \
    -drive if=none,file=$DISK1,id=hd0 -device virtio-blk-device,drive=hd0

Where DISK1 is your EFI ready disk image and QEMU_EFI.fd can be
downloaded from:

http://snapshots.linaro.org/components/kernel/leg-virt-tianocore-edk2-upstream/latest/QEMU-AARCH64/RELEASE_GCC5/QEMU_EFI.fd

See the following for more detailed information:

https://wiki.xenproject.org/wiki/Xen_ARM_with_Virtualization_Extensions/qemu-system-aarch64

Give it a try and let me know if you have any issues.

Cheers,

Stefano
