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.
