问题很简单，但目前很难回答... =-[
我正在尝试按照此处的指示部署 OpenShift (OKD) 4.5 或 4.7指南：安装 OKD 4.5 集群。 看着那（这“启动控制平面节点”部分。
我正在尝试使用UPI（用户配置基础设施）/裸机（KVM）。
问题：
- 版本 4.5
主节点重启后无法完成安装。它一直显示以下错误...
[ 1304.254380] ignition[485]: GET https://api-int.mbr.okd.local:22623/config/master: attempt #92
[ 1314.264629] ignition[485]: GET error: Get "https://api-int.mbr.okd.local:22623/config/master": net/http: timeout awaiting response headers
对于版本 4.5，我们使用“Fedora CoreOS 32.20200715.3.0”。
- 版本 4.7
主节点重启后无法完成安装。它一直显示以下错误...
[ 543.933709] ignition[505]: GET https://api-int.mbr.okd.local:22623/config/master: attempt #112
[ 543.939340] ignition[505]: GET error: Get "https://api-int.mbr.okd.loca1:22623/config/master": EOF
对于版本 4.7，我们使用“Fedora CoreOS 34.20210518.3.0”。
我已经等了好几个小时，主节点仍然处于同样的情况。我该怎么做才能解决这个问题？
谢谢！=D
