scaleway.com 的这个mac m1云电脑从 update.dbankcdn.com 下载的速度太慢了，还看不到模拟器的启动命令

模拟器好像是基于qemu修改的，但参数和普通qemu不一样：

/Applications/DevEco-Studio.app/Contents/tools/emulator/Emulator -hvd Huawei_2in1 -path /Users/m1/.Huawei/Emulator/deployed -t trace_34110_commandPipe -imageRoot /Users/m1/Library/Huawei/Sdk

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：
