主机： Ubuntu14.04 64位版本
模拟器：Qemu-2.8.0
Linux内核版本： Linux-4.10
Busybox版本：busybox-1.24.2
工具链： gcc
模拟一个双核或者单核的x86_64架构的系统，根文件系统用ramdisk的形式，跟Host之间采用NFS的方式实现文件共享。
请参考博文用qemu搭建aarch64学习环境
Ubuntu系统自带的gcc
登录https://www.kernel.org/， 下载最新的Linux版本，目前最新的是Linux-4.10。
下面是编译下面要用的kernel的命令：
1 #!/bin/bash 2 make O=out_x86_64 x86_64_defconfig 3 make O=out_x86_64 menuconfig 4 make O=out_x86_64 bzImage -j8
1 General setup ---> 2 ----> [*] Initial RAM filesystem and RAM disk (initramfs/initrd) support 3 Device Drivers ---> 4 [*] Block devices ---> 5 <*> RAM block device support 6 (65536) Default RAM disk size (kbytes)
这里我们给ramdisk设置的默认大小是64MB
登录https://busybox.net/downloads/下载要用的busybox版本，这里我下的是busybox-1.24.2
这里需要注意的是，由于我们的Host是Ubuntu14.04 64bit，所以用gcc默认编译出的文件只能用于x86_64系统，如果要编译出能在x86上面运行的程序，需要在编译的时候传递必要的参数。
执行make menuconfig，配置下面几项：
1 Busybox Settings ---> 2 Build Options ---> 3 [*] Build BusyBox as a static binary (no shared libs)
1 make -j4 2 make install
下面制作启动用的ramdisk，我把这个过程写成了脚本，如下：
1 #!/bin/bash 2 sudo rm -rf rootfs 3 sudo rm -rf tmpfs 4 sudo rm -rf ramdisk* 5 sudo mkdir rootfs 6 sudo cp ../busybox-1.24.2/_install/* rootfs/ -raf 7 sudo mkdir -p rootfs/proc/ 8 sudo mkdir -p rootfs/sys/ 9 sudo mkdir -p rootfs/tmp/ 10 sudo mkdir -p rootfs/root/ 11 sudo mkdir -p rootfs/var/ 12 sudo mkdir -p rootfs/mnt/ 13 sudo cp etc rootfs/ -arf 14 sudo mkdir -p rootfs/lib64 15 sudo cp -arf /lib/x86_64-linux-gnu/* rootfs/lib64/ 16 sudo rm rootfs/lib/*.a 17 sudo strip rootfs/lib/* 18 sudo mkdir -p rootfs/dev/ 19 sudo mknod rootfs/dev/tty1 c 4 1 20 sudo mknod rootfs/dev/tty2 c 4 2 21 sudo mknod rootfs/dev/tty3 c 4 3 22 sudo mknod rootfs/dev/tty4 c 4 4 23 sudo mknod rootfs/dev/console c 5 1 24 sudo mknod rootfs/dev/null c 1 3 25 sudo dd if=/dev/zero of=ramdisk bs=1M count=32 26 sudo mkfs.ext4 -F ramdisk 27 sudo mkdir -p tmpfs 28 sudo mount -t ext4 ramdisk ./tmpfs/ -o loop 29 sudo cp -raf rootfs/* tmpfs/ 30 sudo umount tmpfs 31 sudo gzip --best -c ramdisk > ramdisk.gz
用到的文件可以到这里下载。
