采用arm64架构的QEMU上的Xen

您好，感谢您阅读并感谢您的回复 .

首先，我试图在aarch64的qemu上运行xen . （基于此链接：Xen ARM with Virtualization Extensions/qemu-system-aarch64）

我正在按照他们的步骤：

QEMU

• git clone https://github.com/qemu/qemu.git

• cd qemu

• ./configure --target-list = aarch64-softmmu

• 制作

LINUX

• git clone git：//git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

• cd linux;

• make ARCH = arm64 defconfig

• make ARCH = arm64

并下载（xenial-server-cloudimg-arm64-uefi1.img）文件我不确定，但这包括ubuntu窗口管理器和根文件系统 .

我用这个命令执行它：

./aarch64-softmmu/qemu-system-aarch64 -machine virt,gic_version=3 -machine virtualization=true \
-cpu cortex-a57 -machine type=virt -nographic \
-smp 4 -m 4000 \
-bios QEMU_EFI.fd \
-kernel ../linux/arch/arm64/boot/Image --append "console=ttyAMA0 root=/dev/vda1" \
-device virtio-blk-device,drive=cloud \
-drive if=none,id=cloud,file=cloud.img \
-netdev user,id=hostnet0,hostfwd=tcp::2222-:22, \
-device virtio-net-device,netdev=hostnet0,mac=7c:4c:58:aa:bb:cc \
-drive if=none,file=./ubuntu-16.04-server-cloudimg-arm64-uefi1.img,id=hd0 \
-device virtio-blk-device,drive=hd0

但是日志表示无法连接到具有超时错误的远程服务器，如下所示

[  330.829794] cloud-init[2872]: 2018-03-18 13:25:42,967 - DataSourceCloudStack.py[CRITICAL]: Giving up on waiting for the metadata from ['http://10.0.2.2/latest/meta-data/instance-id'] after 121 seconds

我不知道ID，PW . 而且我发现使用cloud-init，通常人们在另一个控制台中使用ssh登录 . 但总是说

Permission denied (publickey).

有没有人解决这个问题？

• 如何登录linux？

• 有没有更好的方法在aarch64的qemu上运行xen？
