使用qemu模拟一个运行ubuntu20.04的aarch64位的开发板,使用nat网络,然后通过端口映射的方式在host上使用ssh登录开发板。
#!/bin/bash QEMU=qemu-system-aarch64 sudo $QEMU\ -M virt,gic-version=3,virtualization=on,type=virt \ -cpu cortex-a57 -nographic -smp 4 -m 4096 \ -fsdev local,security_model=passthrough,id=fsdev0,path=/home/pengdonglin/data0/Qemu/share \ -device virtio-9p-pci,id=fs0,fsdev=fsdev0,mount_tag=hostshare \ -drive if=none,file=./ubuntu.img,format=raw,id=hd0 -device virtio-blk-device,drive=hd0 \ -append "noinitrd root=/dev/vda1 rootfstype=ext4 rw console=ttyAMA0" \ -kernel ./linux5.8/out_arm64/arch/arm64/boot/Image \ -netdev user,id=eth0,hostfwd=tcp::8765-:22 -device virtio-net-device,netdev=eth0 \ -nographic
开发板上的ubuntu的网络配置的是dhcp:(https://www.cnblogs.com/pengdonglin137/articles/15002046.html)
pengdl@localhost:~$ cat /etc/systemd/network/80-dhcp.network [Match] Name=eth0 [Network] DHCP=yes
在host上登录开发板:
#!/bin/bash sshpass -p " " ssh pengdl@localhost -p 8765
