Packer VSphere-ISO Centos 7 网络连接出现问题

Question

虽然我刚接触 Packer 和 Kickstart 脚本，但我正尝试在 VSphere 集群中自动设置 CentOS 7（最终是 8）机箱。我的 Packer 代码正在调用 Kickstart 脚本来完成设置，但在网络工作时遇到了问题。由于 ESX 集群中的每个节点都是 6.5.X，我认为不需要 Guest IP hack。

当我运行“packer build --debug”并使用 PACLOG=1 以获得更详细的信息时，我发现我的代码无法完成“等待 IP...”步骤：

==> vsphere-iso: Adding generated Floppy...
==> vsphere-iso: Set boot order...
==> vsphere-iso: Power on VM...
==> vsphere-iso: Waiting 10s for boot...
==> vsphere-iso: Typing boot command...
2020/06/09 18:40:15 packer-builder-vsphere-iso plugin: Special code '<esc>' found, replacing with: CodeEscape
2020/06/09 18:40:15 packer-builder-vsphere-iso plugin: Waiting 1 second
2020/06/09 18:40:20 packer-builder-vsphere-iso plugin: Special code '<enter>' found, replacing with: CodeReturnEnter
2020/06/09 18:40:20 packer-builder-vsphere-iso plugin: Waiting 1 second
2020/06/09 18:40:21 packer-builder-vsphere-iso plugin: [INFO] Waiting for IP, up to total timeout: 30m0s, settle timeout: 5s
==> vsphere-iso: Waiting for IP...
==> vsphere-iso: Post "https://<server name>.com/sdk": EOF
==> vsphere-iso: Step "StepWaitForIp" failed

在虚拟机中运行安装程序（无论是否使用 GUI 安装程序），我都会看到虚拟机中未配置网络（适配器已启动但没有 IP）。由于适配器名称不一致，我尝试让 Packer 使用任何连接的适配器，并使用 DHCP 来简化大规模部署。我尝试过“network --onboot yes --device=link --activate”和“network --onboot yes --activate”以及其他组合。每次在 /etc/sysconfig/network-scripts/ 下都会创建一个文件，但网络仍未建立。

我用硬编码变量替换了 Packer JSON 中的所有变量，但得到的结果相同。

作为验证，我还可以看到临时虚拟机在 VSphere 中被列为属于网络的虚拟机，并且它具有有效的 MAC。

我也尝试确保安装了 open-vm-tools 包，但没有帮助。

有人遇到过这个问题吗？
