尝试在ARM Linux里启动：
#!/bin/bash
export LD_LIBRARY_PATH=/usr/local/lib/aarch64-linux-gnu
args=(
-machine virt
#-cpu cortex-a57
-cpu host
-smp 8,sockets=1,cores=8,threads=1
-m 4096
-enable-kvm
-kernel Image
-initrd ramdisk.img
-drive file=cache.img,format=raw,if=virtio
-drive file=system.img,format=raw,if=virtio
-drive file=vendor.img,format=raw,if=virtio
-drive file=userdata.img,format=raw,if=virtio
-drive file=sys_prod.img,format=raw,if=virtio
-append "console=ttyAMA0 root=/dev/ram0"
-serial stdio
-device virtio-gpu
#-device ramfb
-display gtk
)
exec /usr/local/bin/qemu-system-aarch64 "${args[@]}" "$@"
启动不了，kernel panic：
