无法使用 ssh 登录到 qemu ubuntu 服务器

我正在关注这个教程：https://gist.github.com/georg-hawkins/16ee37063213f348a17717a7007d2c79
除了机器是 arm64。我创建了 cloud.txt（仔细观察缩进）。cloud.txt 如下（出于安全考虑进行了修改）。

#cloud-config
users:
  - name: ckim
    ssh-authorized-keys:
      - ssh-rsa AAAAB3NzaC1yc2EAAAADAQABASLKDjfoIBJLKJFikdsdslfkdjLBIlKDfjlIELfjpQOkcVLKjlkdfk6L7l3CypkhJQt+lPkpT5Rl9q4SVIUUgQmXEbuE11e5Gs9slkdfjlsdfsdgsdVt1HoZriRtgsyxweJx5HQLVvqY6lcPPXhJk/drIeceA8T04oohzWF3nquzaUJJkvOB4aI2i4dqTddN9iOS4c0c+Q4sLSogHRzib77y5T03x7wjvdn+M8LSDKjolIGIflkwjodfLDKjfoq*9023k4j98dkfw09etwerf807cTS2eJHIAkImccuuv/OsmVkTYetpAI86hX79yDMRr3CfS9Pw2g44a4+Cd9RR9K6LhlKhGltON1x/ [email protected]
    sudo: [ 'ALL=(ALL) NOPASSWD:ALL' ]
    group: sudo
    shell: /bin/bash

并运行该命令。

../QEMU/qemu-5.1.0/build/aarch64-softmmu/qemu-system-aarch64 -smp 2 -m 1024 -M virt -cpu cortex-a57 -bios QEMU_EFI.fd -nographic -device virtio-blk-device，drive=image -drive if=none，id=image，file=ubuntu-16.04-server-cloudimg-arm64-uefi1.img -device virtio-blk-device，drive=cloud -drive if=none，id=cloud，file=cloud.img -device virtio-net-device，netdev=user0 -netdev user，id=user0 -nic user，hostfwd=tcp::5022-:22

机器开始安装 ubuntu 16.04，并提示我登录。按照教程的指示，在另一个终端中我执行了

ssh -p 2222[电子邮件保护]

我也尝试了 ckim@localhost，但被拒绝了。但是没有响应（只是超时）。在虚拟机服务器端，我看到打印了此消息（出于安全原因修改了某些部分）。

ubuntu login: ckim
Password:

因此，即使我在 qemu 虚拟机上安装了 ubuntu 服务器，我也无法登录。有人能在这里发现什么问题吗？任何有关如何登录的建议或信息都将不胜感激。

答案1

根据您的 qemu 命令，您将主机端口 5022 映射到客户端口 22，请参阅hostfwd=tcp::5022-:22。

因此您的 ssh 命令应该是ssh -p 5022 ckim@localhost。

和平
