I’m struggling to interpret Xen’s documentation around EFI Guest support on arm64.

You claim that it exists, and sure enough I can find resources for EFI Xen Host, but in

terms of DomU, I see OVMF for x86, but don’t see anything for Arm.

Can you give any pointers?

We have support for UEFI/U-boot in the guest. With that you should be

able to launch a normal GRUB. Would that work for you?
