@m-bers Tried to post this on Macrumors, but my post is under mod review. I was able to get the Arch Linux aarch64 image to boot (using ACVM, but expect it will work with vftool as well)- starting with the generic image, add the virtio, virtio_blk, virtio_pci, and virtio_net modules to mkinitcpio.conf. Rebuild the image with mkinitcpio -P and then install an EFI boot loader with systemd-boot (follow the Arch wiki). Works like a charm for me.

@kuestess Thanks for this, I got it working via https://gist.github.com/thalamus/561d028ff5b66310fac1224f3d023c12

This doesn't not seem like a bug in vftool. A few things to diagnose this: look for virtio in /proc/devices, lsmod, and dmesg. This will tell you if the driver loaded.

ended up compiling a new kernel via the archlinuxarm PKGBUILD here: https://github.com/archlinuxarm/PKGBUILDs/blob/master/core/linux-aarch64/PKGBUILD
Kernel boots now but still won't recognize /dev/vda.
Here are the outputs of the original vftool command, /proc/devices, lsmod, and dmesg:
./vftool -k Image -i initramfs-linux.img -d arm64disk.img -m 8192 -a "root=/dev/vda2 rw console=hvc0" -p 4 -t 0
