ARM64/QEMU - Ubuntu Wiki
https://wiki.ubuntu.com/ARM64/QEMUARM64/QEMU - Ubuntu Wiki. Ubuntu/arm64 can run inside the QEMU emulator. You can either do this fully emulated (e.g. on an x86 host) or, accelerated w/ KVM if you have an arm64 host. This page describes how to do both. I've chosen to describe a UEFI-based system here so I can make use of the kernel on the guest's disk image.
