问题：

我试图使用packer来创建UbuntuServer22.04映像，在使用有效的netplan配置重命名NIC时遇到了问题，然后还安装了一个软件包。

A将背景上需要注意的事项组合在一起：

我正在重命名NIC，因为我试图使用terraform在启动时使用带有云init的proxmox设置NIC配置。当cloud在克隆的映像上运行时，它似乎希望在第一次引导时重命名NIC，并且由于它不能动态地重命名NIC (从eth0到ens18)，所以在云之前需要第二次重新启动-init在VM上设置适当的IP地址。当我希望能够使用terraform旋转一个ubuntu服务器时，这并不理想，因为它需要手动重新启动。

我对Proxmox和云init驱动器/配置设置没有问题，它提供了以下操作系统：

AlmaLinux 8&9
RHEL 7，8，&9
Windows Server 2012、2016、2019和2022 (Cloudbase-init)

他们似乎都接受了terraform发送到proxmox使用的云init配置，一切都很好。所有这些都是为了说明也许proxmox不应该重命名NIC，但是Ubuntu是我第一个有问题的操作系统，目前除了Ubuntu之外，我并不是真的在寻找解决方案。

我需要在VM上安装qemu-guest-agent，以便packer能够从Proxmox中读取IP地址，以便它知道连接到谁。

细节：

如果不指定任何网络设置并让subiquity/netplan提供默认值，我可以安装qemu-guest-agent。当我这样做时，在成功的自动安装上位于/var/log/installer中的最后一个D21显示了下面的网络和软件包配置：

autoinstall:

  network:
    ethernets:
      ens18:
        dhcp4: true
    version: 2
  packages:
  - qemu-guest-agent

我可以使用subiquity/netplan成功地重命名NIC。完成此操作后，它将无法安装QEMU-来宾代理，并导致构建过程失败。下面是我为此使用的配置：

  network:
    ethernets:
      ens18:
        match:
          driver: e1000
        dhcp4: true
        set-name: eth0
    version: 2
  packages:
  - qemu-guest-agent

上面的network:块成功地将NIC重命名为eth0，并且我已经在损坏的安装上建立了完整的网络。我能够平一些东西，如google.com，也可以SSH进入机器。我可以从日志中看到重命名是成功的，并且当失败的安装将我弹入shell时，我可以验证新的NIC名称。

下面是NIC重命名之后会遇到的错误。

在不重命名NIC的情况下，在自动安装上运行时，同样的步骤/配置是成功的：

此时，我不太清楚为什么它声明在NIC被重命名后无法定位包。我在这一点上有点困惑，因为在我被呈现外壳之后，VM确实有完整的互联网访问权限。

任何类型的帮助/故障排除步骤都会受到欢迎。很高兴提供任何我能提供的信息。

我喜欢使用late-commands配置网络。

#cloud-config
autoinstall:
  late-commands:
    - |
      rm /target/etc/netplan/00-installer-config.yaml
      cat < /target/etc/netplan/80-my.yaml
      network:
        ethernets:
          ens18:
            match:
              driver: e1000
            dhcp4: true
            set-name: eth0
        version: 2
      EOF

how它工作在

如果您的network文件中没有user-data配置块，那么安装程序(subiquity)将使用通用网计划配置。稍后，subiquity将为已安装的系统生成一个netplan配置，并将其用于安装程序环境。在late-commands中，您可以删除生成的subiquity配置，并将其替换为您想要的任何配置。这只会影响已安装的系统。

我想为其他可能遇到类似问题的人添加更多的信息。我的主要帖子在某些领域是不正确的，因为我已经解决了我的问题，并且知道出了什么问题。

首先，安德鲁的回答将解决在帖子中提出的问题。但我确实明白了为什么我的云-init没有在他的帮助下启动。

在云-init日志中，我最初看到的一些东西使我认为NIC不能用云init重命名，这就是为什么我想重命名NIC并遇到所有这些问题。但这是不对的。

一旦我用Andrew的配置启动了克隆，NIC被重命名了，我意识到即使在连续重新启动之后，它也总是在拉动DHCP配置。在深入研究之后，我意识到云init确实与netplan交互(这就是为什么它不同于我列出的所有其他操作系统)。

我发现这种情况发生在云-init中，显示它在某些情况下与netplan交互：

Sep  6 00:23:13 ubuntu22 cloud-init[773]: 2022-09-06 00:23:08,634 - util.py[DEBUG]: Writing to /etc/netplan/50-cloud-init.yaml - wb: [644] 695 bytes
Sep  6 00:23:13 ubuntu22 cloud-init[773]: 2022-09-06 00:23:08,636 - subp.py[DEBUG]: Running command ['netplan', 'generate'] with allowed return codes [0] (shell=False, capture=True)
Sep  6 00:23:13 ubuntu22 cloud-init[773]: 2022-09-06 00:23:09,030 - subp.py[DEBUG]: Running command ['udevadm', 'test-builtin', 'net_setup_link', '/sys/class/net/eth0'] with allowed return codes [0] (shell=False, capture=True)
Sep  6 00:23:13 ubuntu22 cloud-init[773]: 2022-09-06 00:23:09,049 - subp.py[DEBUG]: Running command ['udevadm', 'test-builtin', 'net_setup_link', '/sys/class/net/lo'] with allowed return codes [0] (shell=False, capture=True)

因此，为了使云init能够正确地设置网络配置，我最终需要删除内置安装程序netplan配置，并重新安装/清理云init。下面是我在ansible中使用的步骤：

    - name: Run cloud-init clean
      ansible.builtin.shell: cloud-init clean
      when: ansible_distribution == "Ubuntu"

    - name: Remove cloud-init
      ansible.builtin.apt:
        name: cloud-init
        state: absent
      when: ansible_distribution == "Ubuntu"

    - name: Remove /etc/cloud
      ansible.builtin.shell: rm -rf /etc/cloud
      when: ansible_distribution == "Ubuntu"

    - name: Remove /var/lib/cloud
      ansible.builtin.shell: rm -rf /var/lib/cloud
      when: ansible_distribution == "Ubuntu"

    - name: Reboot the Ubuntu VM
      ansible.builtin.reboot:
      when: ansible_distribution == "Ubuntu"

    - name: Install cloud-init
      ansible.builtin.apt:
        name: cloud-init
        state: latest
      when: ansible_distribution == "Ubuntu"

    - name: Remove netplan file
      ansible.builtin.shell: rm -f /etc/netplan/00-installer-config.yaml
      when: ansible_distribution == "Ubuntu"
      ignore_errors: yes

上面附有一个自动安装配置，它排除了我认为需要的整个network:块(因此允许subiquity生成它)。

else
menuentry 'Test memory' {

您的以太网卡将在安装grub中命名为eth0，并带有"net.ifnames=0 biosdevname=0“。
