1. 环境安装好vmware ，里面装个linux系统，比如ubuntu

2. 虚拟机里面安装qemu 

sudo apt update
sudo apt install qemu qemu-kvm libvirt-daemon-system libvirt-clients bridge-utils virt-manager

3. 虚拟机里面git下载Xv6 
git clone https://github.com/mit-pdos/xv6-riscv.git

4. 进入xv6-riscv，执行make qemu命令，就可以直接跑起来xv6系统了

如果报错，就安装对应的包

sudo apt install binutils-riscv64-linux-gnu
sudo apt install gcc-riscv64-linux-gnu
sudo apt install gdb-multiarch
sudo apt install qemu-system-misc opensbi u-boot-qemu qemu-utils

./configure --target-list=riscv64-softmmu
make -j$(nproc)
sudo make install

①qemu：
wget https://download.qemu.org/qemu-9.1.1.tar.xztar xvJf qemu-9.1.1.tar.xzcd qemu-9.1.1sudo apt install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev \gawk build-essential bison flex texinfo gperf libtool patchutils bc \zlib1g-dev libexpat-dev git \libglib2.0-dev libfdt-dev libpixman-1-dev \libncurses5-dev libncursesw5-dev./configure --prefix=/opt/qemu --target-list=riscv64-softmmu,riscv64-linux-user
（如果缺少包报错，就把包安装就行）make -j $(nproc)sudo make installqemu-system-riscv64 -version
（这里可能输出的是6.2.0版本的）/opt/qemu/bin/qemu-system-riscv64 --version
（这个测试以下，看qemu版本是不是9.1.1）export PATH=/opt/qemu/bin:$PATH
qemu-system-riscv64 -version
（执行这一条，重新看版本是不是变了）②RISC-V 工具链
sudo apt install gcc-riscv64-unknown-elf
（我是ubuntu22.04，可以用这个直接下载。可以问一下gpt看能不能用这个，不能的话就很麻烦，先省略）③xv6-riscv（先确定前面的qemu版本是对的）
git clone https://github.com/mit-pdos/xv6-riscv.git
cd xv6-riscv
make
make qemu
