I have a script that creates a number of image files and a number of qemu
scripts that look
like the following:

/home/imp/git/qemu/00-build/qemu-system-aarch64 -nographic -machine
virt,gic-version=3 -m 512M -smp 4 \
        -cpu cortex-a57 \
        -drive
file=/home/imp/stand-test-root/images/arm64-aarch64/linuxboot-arm64-aarch64-zfs.img,if=none,id=drive0,cache=writeback
\
        -device virtio-blk,drive=drive0,bootindex=0 \
        -drive
file=/home/imp/stand-test-root/bios/edk2-arm64-aarch64-code.fd,format=raw,if=pflash
\
        -drive
file=/home/imp/stand-test-root/bios/edk2-arm64-aarch64-vars.fd,format=raw,if=pflash
\
        -monitor telnet::4444,server,nowait \
        -serial stdio $*

There's a list of these files that's generated and looks to see if it gets
to the 'success' echo in the minimal root I have for them.
