This is the exact virt-install command I used:

  $ virt-install \
    --cpu cortex-a53 \
    --name alpine-aarch64 \
    --cdrom ~/Downloads/alpine-virt-3.11.2-aarch64.iso \
    --disk size=8 \
    --vcpus 4 \
    --memory 2048 \
    --os-variant alpinelinux3.8 \
    --arch aarch64 \
    --boot loader=/usr/share/edk2/aarch64/QEMU_EFI-pflash.raw,loader.readonly=yes,loader.type=pflash,nvram.template=/usr/share/edk2/aarch64/vars-template-pflash.raw,loader_secure=no

The '--boot ...' part is only necessary because of an issue in
current libvirt that's already being worked on.

Here's the full XML:
