前言

  • mips: 32位大端序
  • mipel: 32位小端序
  • mips64el: 64位小端序

安装工具

1
apt install qemu-system-mips libguestfs-tools

	-m 1024 \
	-cpu 5KEc \
	-kernel vmlinuz-6.1.0-35-5kc-malta \
	-initrd initrd.gz \
	-drive if=none,file=hda.qcow2,format=qcow2,id=hd \
	-device virtio-blk-pci,drive=hd \
	-netdev user,id=qemunet \
	-device virtio-net-pci,netdev=qemunet \
	-nographic \
	-no-reboot \
	-append "console=ttyS0"

之后就是debian的安装流程，安装完成后就可以把vmlinuz-6.1.0-35-5kc-malta和initrd.gz删掉了。
