使用Qemu模拟Numa机器

用Qemu模拟一个下面的Numa架构：

启动命令如下：

#!/bin/bash

QEMU=qemu-system-aarch64

sudo $QEMU\
    -M virt,gic-version=3,virtualization=on,type=virt \
    -cpu cortex-a57 -nographic -m 4G \
    -smp cores=4,threads=1,sockets=2 \
    -object memory-backend-ram,id=mem0,size=2G  \
    -object memory-backend-ram,id=mem1,size=2G  \
    -numa node,memdev=mem0,cpus=0-3,nodeid=0 \
    -numa node,memdev=mem1,cpus=4-7,nodeid=1 \
    -fsdev local,security_model=passthrough,id=fsdev0,path=/home/pengdonglin/data0/Qemu/share \
    -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare \
    -drive if=none,file=./ubuntu.img,format=raw,id=hd0 -device virtio-blk-device,drive=hd0 \
    -append "noinitrd root=/dev/vda1 rootfstype=ext4 rw console=ttyAMA0" \
    -kernel ./linux5.8/out_arm64/arch/arm64/boot/Image \
    -netdev user,id=eth0,hostfwd=tcp::8765-:22 -device virtio-net-device,netdev=eth0 \
    -nographic

完。
