在没有aarch64架构的开发板的情况下，可以使用Qemu来模拟一个支持KVM的AArch64位的host，然后再在其上运行一个开启KVM加速的Qemu虚拟机，如下图所示：

软件版本如下：

1： x86_64上运行的是ubuntu20.04

2：qemu版本是5.1.0，ubuntu16.04，内核版本5.8，因为要编译运行在aarch64上qemu版本， 所以这里使用了ubuntu文件系统（可以参考https://www.cnblogs.com/pengdonglin137/p/9540670.html）

3和4：qemu版本是4.1.0, 内核版本5.8，为了加快虚拟机的启动速度，这里使用ramdisk文件系统

启动2的命令如下：

!/bin/bash

QEMU=/home/pengdl/work1/Qemu/qemu-5.1.0/build/bin/qemu-system-aarch64

sudo $QEMU\

    -M virt,gic-version=3,virtualization=on,type=virt \

    -cpu cortex-a57 -nographic -smp 8 -m 8800 \

    -fsdev local,security_model=passthrough,id=fsdev0,path=/home/pengdl/kvm_study/share \

    -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare \

    -drive if=none,file=./ubuntu_40G.ext4,format=raw,id=hd0 -device virtio-blk-device,drive=hd0 \

    -append "noinitrd root=/dev/vda rootfstype=ext4 rw" \

    -kernel ./Image \

    -nic tap \

    -nographic

启动3和4的命令如下：

#!/bin/bash

sudo /home/pengdl/qemu-5.1.0/build/bin/qemu-system-aarch64 \

        -M virt,gic-version=3,accel=kvm \

        -cpu cortex-a57 -nographic -smp 2 -m 4000  \

        -fsdev local,security_model=passthrough,id=fsdev0,path=/home/pengdl/share \

        -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare \

        -append "root=/dev/ram0 rw rootfstype=ext4 console=ttyAMA0 init=/linuxrc" \

        -initrd ./ramdisk.img \

        -kernel ./Image \

        -nographic

AArch64的Host和Guest使用的使用了相同的内核镜像，使用arm64的默认配置编译，如果要支持ramdisk文件系统的话，还需要调整一下配置。

编译运行在x86上的qemu的命令如下：

#!/bin/bash

../configure --prefix=`pwd` \

    --target-list=arm-softmmu,aarch64-softmmu,i386-softmmu,x86_64-softmmu,riscv32-softmmu,riscv64-softmmu,aarch64-linux-user,arm-linux-user,riscv64-linux-user,x86_64-linux-user \

    --audio-drv-list=alsa,sdl,pa \

    --enable-system \

    --enable-user \

    --enable-linux-user \

    --enable-sdl \

    --enable-vnc \

    --enable-virtfs \

    --enable-kvm \

    --enable-fdt \

    --enable-debug \

    --disable-strip \

    --enable-debug-tcg \

    --enable-debug-info

编译运行在aarch64上的qemu的命令如下:

#!/bin/bash

../configure --prefix=`pwd` \

    --target-list=aarch64-softmmu \

    --enable-kvm \

    --enable-virtfs

Host的启动log：
