在xen virt平台运行xen

1）安装编译器：

sudo apt install gcc-aarch64-linux-gnu

2）构建uboot源码：

make CROSS_COMPILE=aarch64-linux-gnu- qemu_arm64_defconfig

make CROSS_COMPILE=aarch64-linux-gnu- -j4

3）编译设备树：

dtc -I dts -O dtb -o virt-gicv3.dtb virt-gicv3.dts

4）编译xen：

cd stout_xen

XEN_TARGET_ARCH=arm64 ./configure

启动调试选项：

cd xen
make menuconfig XEN_TARGET_ARCH=arm64

    Debugging Options  --->

        [*]	  Developer Checks

		[*]   Early printk (Early printk via PL011 UART)  --->           │ │  

  │ │    (0x9000000) Early printk, physical base address of debug UART

编译xen：

cd ../

make xen XEN_TARGET_ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- debug=y -j4

制作Xen uImage镜像:

mkimage -A arm -T kernel -a 0x40200000 -e 0x40200000 -C none -d xen/xen xen/xen-uImage

5）在qemu上运行xen

u-boot启动xen：

qemu-system-aarch64 -machine virt -machine virtualization=true -cpu cortex-a57 -machine type=virt -m 2048 -smp 4 -bios u-boot.bin -device loader,file=xen,force-raw=on,addr=0x40200000 -device loader,file=virt-gicv3.dtb,addr=0x44000000 -nographic
